Kuv nco qab thawj zaug uas tus neeg siv khoom nug kuv tias vim li cas peb tsis muag HMPSA hauv daim ntawv pellet. Nws tau sawv hauv peb lub Hoobkas, saib cov neeg ua haujlwm thauj cov blocks rau hauv lub melter, thiab nws hais tias, "Tab sis cov pellets yooj yim dua, puas yog? Less mess?"
Lo lus teb tsis yooj yim li ntawd.
Tom qab 20 xyoo ntawm kev tsim cov kub yaj siab rhiab nplaum nplaum, peb tau pom ob daim ntawv ua haujlwm zoo nkauj -thiab ua tsis tau zoo. Qhov tseeb yog, xaiv ntawm thaiv thiab pellet tsis yog hais txog kev yooj yim. Nws yog hais txog kev sib piv daim ntawv nplaum rau cov khoom siv thiab koj cov kev xav tau ntau lawm.
Cia kuv taug kev koj los ntawm qhov peb tau kawm los ntawm kev muab ntau dua 3,800 tus neeg siv khoom thoob plaws 23 lub xeev.
Physics Teeb meem nrog Pelletized HMPSA
Nov yog qee yam uas cov neeg siv khoom nplaum feem ntau yuav tsis qhia rau koj: HMPSA yog qhov nplaum nplaum. Qhov ntawd yog qhov tseeb nws txoj haujlwm- kom nyob twj ywm ntawm chav tsev kub thiab kev sib raug zoo nrog lub teeb siab.
Tam sim no sim txiav cov khoom nplaum rau hauv cov pellets me me. Yuav ua li cas? Lawv lo ua ke. Thaum lub sij hawm cia, thaum shipping, txawm nyob rau hauv lub hnab. Koj qhib ib lub hnab 25kg ntawm HMPSA pelletized tom qab ib hlis, thiab koj tab tom saib cov pob khoom.
Kev kub yaj nplaum nplaum (EVA-raws li, tsis yog- siab rhiab) tsis muaj qhov teeb meem no. Thaum nws txias, nws qhuav. Koj tuaj yeem pelletize nws, ntim nws, khaws cia rau rau lub hlis, thiab nws tseem yuav ntws zoo li ib tus neeg pellets.
Tab sis HMPSA? Dab neeg sib txawv.
Yog li cov tuam txhab uas muag pelletized HMPSA yuav tsum tau siv cov tshuaj tiv thaiv-tack txheej rau txhua tus pellet. Xav txog nws zoo li plua plav cov khoom qab zib nplaum nrog hmoov qab zib kom cov khoom tsis sib xyaw. Cov txheej ntawd melts rau hauv koj cov nplaum nplaum thaum lub sij hawm thov, muaj peev xwm hloov cov formulation.
Peb tau muaj cov neeg muas zaub hloov los ntawm pelletized HMPSA rau peb daim ntawv thaiv thiab tshaj tawm 30% tsawg lub nozzle clogging nyob rau hauv thawj lub hlis.
Vim Li Cas Block Form Dominates HMPSA Applications
Thaum peb tsim HMPSA, nws tawm ntawm lub reactor raws li qhov kub thiab txias. Peb ncuav nws rau hauv pwm, cia nws txias rau hauv cov khoom blocks (feem ntau 20-25 kg txhua), thiab qhwv txhua qhov thaiv hauv ib zaj duab xis nyias nyias.
Cov zaj duab xis wrapper yog engineered kom yaj ntawm tib qhov kub thiab txias li cov nplaum nws tus kheej. Koj muab tag nrho cov qhwv thaiv rau hauv lub tank melter. Tsis muaj unwrapping, tsis tuav cov khoom nplaum, tsis muaj pov tseg.
Cov yeeb yaj kiab yog co-extruded- txhais tau tias nws tau sib xws nrog cov nplaum nplaum. Nws tsis hloov lub tack, tev lub zog, los yog viscosity. Nws tsuas yog ploj mus rau hauv lub yaj.
Qee tus neeg muag khoom siv silicone -coated tso lub thawv hloov. Lub thawv tuav lub thaiv thaum thauj khoom, thiab koj tso tag nrho lub thawv rau hauv lub melter. Cov txheej silicone tiv thaiv tsis txhob lo, thiab lub thawv melts huv si.
Ob txoj kev ua haujlwm. Tab sis qhwv cov blocks yog tus nqi ntau dua - siv tau rau siab - ntim ntau lawm vim tias koj tsis them rau lub thawv nruj.
Tiag -Kev Sib Piv Kev Ua Haujlwm Hauv Ntiaj Teb
Cia kuv qhia qee cov ntaub ntawv los ntawm cov neeg siv khoom uas tau siv ob daim ntawv.
Case 1: Chaw tsim tshuaj paus nyob rau hauv Jiangsu Province
Lawv pib nrog HMPSA pelletized los ntawm ib lub chaw muag khoom hauv zos. Txhua tag kis sawv ntxov, cov neeg ua haujlwm yuav tsum tau rhuav tshem cov kab hauv lub hopper pub. Cov tshuaj tiv thaiv -tack txheej tau ua rau muaj cov kab nrib pleb ntawm cov tshuaj tsuag nozzle. Tom qab hloov mus rau peb cov thaiv thaiv HMPSA, lawv txo qis txij li 2 teev hauv ib lub lis piam mus rau 15 feeb.
Case 2: Express hnab Hoobkas hauv Guangdong
Lawv sim pelletized HMPSA vim tias nws yog 8% pheej yig dua ib kilogram. Tab sis cov txheej txheej paug ua rau tsis sib haum tack thoob plaws lub hnab ntim khoom. Lawv muaj 3% tsis lees paub tus nqi ntawm tamper-cov ntaub ntawv pov thawj. Hloov rov qab mus rau daim ntawv thaiv, qhov kev tsis lees paub poob rau 0.2%.
Case 3: Hygiene khoom chaw tsim tshuaj paus nyob rau hauv Zhejiang
Lawv xav tau kev kho mob -qib HMPSA rau tus menyuam daim ntaub qhwv elastic. Pelletized versions muaj nyob rau hauv kev ua lag luam muaj txheej txheej residues uas ua tsis tau tejyam ntawm daim tawv nqaij kev ntsuam xyuas. Thaiv daim ntawv HMPSA nrog meltable wrapper zaj duab xis dhau tag nrho cov kev cai biocompatibility.
Thaum Pellet Ua Tau Zoo
Kuv tsis hais pellets yeej phem. Rau cov uas tsis yog- cov nplaum nplaum nplaum nplaum nplaum nplaum zoo li -zoo li EVA kub yaj rau ntug banding lossis ntim khoom - pellets yog qhov zoo tagnrho. Lawv yooj yim los tswj, ntsuas qhov tseeb, thiab khaws cia ntev -lub sij hawm yam tsis muaj teeb meem.
Yog tias koj daim ntawv thov siv cov nplaum uas tsis yog -tacky, pellets yog qhov kev xaiv zoo dua. Tab sis yog tias koj xav tau lub zog rhiab heev (tack mus tas li, kev sib txuas tam sim, tamper- pov thawj sealing), daim ntawv thaiv yog tus qauv kev lag luam rau qhov laj thawj zoo.
Kev tuav thiab khaws cia: Thaiv daim ntawv zoo tshaj plaws
Txawm hais tias thaiv daim ntawv HMPSA yog yooj yim los lis dua pelletized HMPSA, koj tseem yuav tsum ua raws li qee cov cai yooj yim:
Cia kub:Khaws cov blocks hauv qab 35℃hauv qhov chaw qhuav, qhov cua. Peb tau pom cov blocks deform thiab fuse ua ke thaum stacked siab heev nyob rau hauv ib tug kub warehouse thaum lub caij ntuj sov.
Stacking qhov siab:Tsis txhob ntim ntau tshaj 3 pallets siab. Qhov hnyav ntawm cov blocks hauv qab tuaj yeem ua rau "txias ntws" - qeeb deformation hauv siab.
Lub neej txee:Kev khaws cia kom raug, peb cov HMPSA thaiv kev ua haujlwm tau 12 lub hlis. Peb pom zoo FIFO (ua ntej hauv, ua ntej tawm) cov khoom xa tuaj.
Premelting:Rau siab - cov kab ceev, siv lub nruas unloader los yog premelter tank. Tsis txhob sim yaj cov blocks txias ncaj qha rau hauv daim ntawv thov me me tank. Qhov kub poob yuav cuam tshuam cov txheej txheej uniformity.
Tus nqi suav tsis muaj leej twg hais txog
Cia peb tau txais tiag tiag txog tus nqi. Thaiv daim ntawv HMPSA zoo li kim dua ib kilogram dua pelletized versions. Tab sis ntawm no yog dab tsi tus nqi tag tsis qhia:
Anti-tack txheej ntawm pellets ntxiv 5-8% rau cov khoom siv
Coating contamination tsub kom kev tu ntau zaus
Qhov zoo ntawm melting tsis zoo ua rau muaj kev tsis lees paub ntau dua
Lub sijhawm tus neeg teb xov tooj siv los rhuav tshem pawg
Thaum koj xam tag nrho tus nqi ntawm kev ua tswv cuab-tsis yog tus nqi ib kg nkaus xwb- daim ntawv thaiv HMPSA feem ntau tawm ua ntej.
Ib qho ntawm peb cov neeg siv khoom tau ua qhov kev soj ntsuam ntxaws. Lawv piv pelletized HMPSA ntawm ¥18/kg vs. peb daim ntawv thaiv ntawm ¥19.5/kg. Tom qab kev txhim kho hauv kev saib xyuas kev poob qis, tus nqi tsis lees paub, thiab cov neeg ua haujlwm ua haujlwm, daim ntawv thaiv yog ¥ 0.80 / kg pheej yig dua hauv cov nqi tsim khoom tiag.
Yuav ntsuas cov neeg muab khoom li cas
Yog tias koj tab tom siv pelletized HMPSA thiab txiav txim siab hloov mus rau daim ntawv thaiv, ntawm no yog dab tsi nug cov neeg xa khoom muaj peev xwm:
1. Lub wrapper zaj duab xis yog dab tsi? Nws puas yog co-extrudable thiab tag nrho sib xws nrog cov nplaum?
2. Koj puas tuaj yeem muab cov qauv rau kev kuaj kab ntau lawm? (Tsis yog kuaj kuaj xwb)
3. Dab tsi yog qhov koj pom zoo cia thiab tuav txheej txheem?
4. Koj puas muaj kev txhawb nqa rau kev daws teeb meem thaum lub sijhawm hloov?
5. Koj puas tuaj yeem hloov kho qhov loj me lossis wrapper zaj duab xis melting point rau peb cov khoom tshwj xeeb?
Peb ib txwm xa cov qauv ua ntej. Peb xav siv sijhawm ib lub lim tiam sim ntawm koj txoj kab dua li xa koj 10 tons ntawm cov nplaum uas tsis ua haujlwm hauv koj qhov kev teeb tsa tshwj xeeb.
Ua Tus Hloov: Yuav Ua Li Cas
Kev hloov ntawm pelletized rau thaiv daim ntawv HMPSA tsis nyuaj, tab sis nws yuav tsum tau hloov qee yam:
Lub Limtiam 1:Ntxuav koj lub tank kom huv si. Tshem tawm cov khoom seem ntawm pellet coatings.
Lub Limtiam 2:Nruab ib lub premelter yog tias koj tsis muaj. Thaiv daim ntawv ua haujlwm zoo tshaj plaws nrog maj mam preheating.
Lub Limtiam 3:Khiav kev xeem batch. Kho qhov kub thiab txias raws li qhov thaiv cov yam ntxwv melting.
Lub Limtiam 4:Kev tsim tawm tag nrho. Saib xyuas qhov mob nozzle thiab tack sib xws.
Cov neeg siv khoom feem ntau tau ua haujlwm tag nrho hauv ib hlis. Thiab yuav luag txhua tus qhia peb ib yam: "Kuv xav tias peb yuav hloov sai dua."
Kev xav zaum kawg
Qhov kev xaiv ntawm thaiv thiab pellet tsis yog hais txog qhov twg zoo dua. Nws yog hais txog daim ntawv twg phim koj cov nplaum chemistry thiab kev xav tau ntau lawm.
Rau HMPSA tshwj xeeb, daim ntawv thaiv yog tus qauv pov thawj. Nws ua haujlwm ntawm cov khoom siv los ntawm tackiness, txo qhov kev pheej hmoo ntawm kev kis kab mob, thiab muab kev ua haujlwm zoo ib yam.
Yog tias koj tam sim no tawm tsam nrog HMPSA pelletized-clumping, txheej residue, tsis sib haum tack-tej zaum nws yog lub sij hawm los xav txog.
Peb tsim cov khoom thaiv -form HMPSA rau cov ntawv lo, daim kab xev, cov hnab nthuav qhia, thiab cov khoom siv tu cev. Yog tias koj xav sim peb cov nplaum ntawm koj txoj kab, ncav cuag. Peb mam li xa cov qauv thiab kev txhawb nqa kom paub tseeb tias qhov kev hloov mus tau zoo.
