Lub tshuab nqus tsev tsim, raws li kev ua tau zoo thiab tsis tshua muaj nqi- thev naus laus zis thev naus laus zis, yog siv dav hauv kev ntim khoom, tsheb, khoom siv hauv tsev, kev kho mob, thiab lwm yam kev lag luam vim nws qhov zoo ntawm cov pwm pwm tsawg thiab cov voj voog luv luv. Kev xaiv ntawm cov ntaub ntawv ncaj qha txiav txim siab qhov zoo, kev ua tau zoo, thiab cov xwm txheej siv tau ntawm cov khoom molded. Ntawm lawv, ABS, PVC, PET (PETG), thiab HDPE cov ntaub ntawv yog plaub cov ntaub ntawv nyiam tshaj plaws rau lub tshuab nqus tsev vim lawv muaj zog yoog raws thiab zoo heev molding nyhuv. Kab lus no yuav tshuaj xyuas kom meej cov yam ntxwv, molding zoo, thiab raug siv ntawm plaub hom ntawv, muab ib tug siv rau kev lag luam xaiv.
ABS ntawv
ABS (acrylonitrile-butadiene-styrene copolymer) daim ntawv yog ib qho ntawm cov ntawv siv dav tshaj plaws hauv lub tshuab nqus tsev ua teb, muaj kev sib xyaw ua ke ntawm toughness, hardness, thiab rigidity, ua qhov tseeb "tag nrho-rounder." Nws cov txiaj ntsig tseem ceeb yog nyob rau hauv nws qhov zoo molding fluidity, zoo li softening tom qab cua sov, meej conformability rau cov zoo textures ntawm complex pwm, siab molding raug, thiab muaj zog seem stability tom qab txias, ua rau nws resistant rau deformation. Lub caij no, cov nplooj ntawv ABS muaj qhov cuam tshuam lub zog 3-5 npaug ntawm cov yas zoo tib yam, siab tawv tawv, khawb tsis kam, thiab tshuaj tiv thaiv corrosion. Lawv tuaj yeem ua tiav ntxiv los ntawm kev pleev xim, luam ntawv, thiab lwm yam, muab kev zoo nkauj zoo nkauj ntau yam. Nyob rau hauv daim ntawv thov scenarios, versatility ntawm ABS cov ntaub ntawv yog tag nrho qhia: kev lag luam automotive siv lawv los tsim dashboards, lub qhov rooj vaj huam sib luag liner, cua txias vents, thiab lwm yam sab hauv; kev lag luam khoom siv hauv tsev siv lawv los ua cov khoom siv tub yees, lub tshuab ntxhua khaub ncaws, thiab cov tshuab cua txias; Tsis tas li ntawd, cov cuab yeej siv kho mob, cov khoom ua si plhaub, thiab cov thawv ntawv tshaj tawm kuj tseem siv cov ntawv ABS rau lub tshuab nqus tsev, ua rau lawv tshwj xeeb tshaj yog haum rau cov xwm txheej nrog ob qhov kev xav tau rau kev tsim lub zog thiab kev zoo nkauj zoo nkauj.
PVC ntawv
Cov ntawv PVC (polyvinyl chloride) tau dhau los ua cov khoom siv tseem ceeb rau lub tshuab nqus tsev vim lawv cov nqi siab -kev ua tau zoo thiab kev siv dav. Lawv tau muab faib ua hom mos thiab nruj, nrog cov ntaub ntawv PVC tawv tau siv ntau dua hauv kev tsim khoom. Lawv qhov zoo tshaj plaws suav nrog cov cua kub uas tsis tshua muaj cua sov (kwv yees li 70-100 degree), kev siv hluav taws xob tsawg, thiab tus nqi tsuas yog 60%-70% ntawm cov ntawv ABS, ua rau lawv tsim nyog rau kev tsim khoom loj ntawm tus nqi qis. Lub caij no, cov nplooj ntawv PVC tiv taus cov kua qaub thiab alkali corrosion, muaj rwb thaiv tsev zoo, thiab du, tiaj tus. Tom qab molding, lawv yuav tsum tsis muaj cov ncej nyuaj- ua kom tau raws li cov kev cai siv yooj yim. PVC daim ntawv thov yog tsom rau cov nqi-sensitive scenarios nrog cov kev xav tau ntawm kev ua haujlwm nruab nrab: blister tais hauv kev lag luam ntim khoom noj, cov khoom ntim khoom tshiab rau lub khw muag khoom; hniav vaj huam sib luag thiab qhov cua ducts hauv kev tsim kho kev lag luam; thiab anti-static ntim cov tais rau cov khoom siv hluav taws xob. Cov nplooj ntawv PVC yooj yim kuj tuaj yeem siv los tsim cov npog yooj yim tiv thaiv thiab ntim tau yooj yim, txuas ntxiv nthuav lawv cov kev hloov pauv.
PET Ntawv
PET thiab hloov kho cov nplooj ntawv PETG yog cov khoom siv zoo tshaj plaws rau lub tshuab nqus tsev vim lawv cov phooj ywg ib puag ncig thiab siab pob tshab. Cov ntawv PET muaj lub teeb pom kev zoo (txog li 90% lossis ntau dua), mus txog ntawm iav thaum sib dua. Lawv kuj muaj kev cuam tshuam -resistant, tshav kub-resistant (sab 80-100 degree), tshuaj lom neeg ruaj khov, thiab rov ua dua tshiab, ua raws li cov tswv yim ntsuab tsim tam sim no. Hloov kho cov nplooj ntawv PETG khaws qhov zoo ntawm PET thaum ntxiv kev txhim kho molding fluidity thiab qis -kub molding kev ua tau zoo, ua rau lawv tsis tshua muaj kev tawg thiab dawb. Lawv cov ntawv thov siab- kawg yog cov tseem ceeb hauv thaj chaw uas yuav tsum tau nruj rau kev pom tseeb thiab ib puag ncig tus phooj ywg: high-end blister packs thiab dej haus preforms hauv ntim khoom noj; pob tshab ntim thawv thiab tso saib racks hauv kev lag luam tshuaj pleev ib ce; pob tshab tiv thaiv npog thiab cov khoom siv kuaj cov plhaub hauv cov khoom siv kho mob; thiab pob tshab plhaub thiab tso saib cov yeeb yaj kiab tiv thaiv rau cov khoom siv hluav taws xob. Lub zog siab thiab huab cua tsis kam ntawm cov ntawv PET kuj ua rau lawv nrhiav tau zoo heev hauv cov thawv sab nraum zoov thiab cov khoom siv.
HDPE ntawv
HDPE (High-Density Polyethylene) cov ntawv yog nyiam nyob rau hauv tshwj xeeb lub tshuab nqus tsev molding daim ntaub ntawv vim lawv superior corrosion kuj thiab zoo heev toughness, ua rau lawv ib tug tseem ceeb cov ntaub ntawv rau industries xws li tshuaj thiab tshuaj. Lawv muaj cov tshuaj lom neeg ruaj khov heev, tiv thaiv kev tawm tsam corrosive xws li cov kua qaub muaj zog, muaj zog alkalis, thiab cov kuab tshuaj organic. Lawv kuj qhia tau zoo heev uas tsis tshua muaj - kub toughness, tuav zoo cuam tshuam lub zog txawm nyob rau ntawm -40℃thiab tiv taus brittleness. HDPE cov ntaub ntawv tseem tsis muaj dej tsis zoo, noo noo- pov thawj, tsis yog - tshuaj lom, thiab tsis muaj ntxhiab, nrog kev ruaj khov thaum lub sij hawm molding, ua rau lawv tsim nyog rau kev tsim khoom loj, yooj yim- cov qauv pwm. Nws cov ntawv thov yog txawv ntawm kev lag luam- tshwj xeeb: cov kab hauv lub tank, cov kav dej tiv thaiv corrosion, thiab cov khoom siv raw khoom ntim pallets hauv kev lag luam tshuaj; aseptic ntim ntim thiab cov khoom siv kho mob pallets hauv kev lag luam kws tshuaj; acid thiab alkali resistant khoom plhaub thiab conveyor accessories nyob rau hauv cov khoom noj khoom haus kev lag luam; thiab kev tiv thaiv vaj huam sib luag rau kev txuag dej sab nraum zoov thiab cov khoom siv dej hauv cov khoom siv ua liaj ua teb. Lub durability ntawm HDPE nplooj ntawv ua rau lawv muaj kev ntseeg siab xaiv rau lub tshuab nqus tsev nyob rau hauv ib puag ncig hnyav.
Qhov sib txawv ntawm cov yam ntxwv ntawm plaub hom ntawv txheeb xyuas lawv daim ntawv thov ciam teb: ABS cov ntawv raug xaiv rau tag nrho cov kev ua tau zoo thiab cov tsos; PVC ntawv yog xaiv rau kev tswj tus nqi; Cov ntawv PET raug xaiv kom pom tseeb thiab ib puag ncig tus phooj ywg; thiab cov ntawv HDPE raug xaiv rau corrosion thiab tsawg- qhov kub thiab txias ib puag ncig. Hauv kev tsim khoom tiag tiag, kev txiav txim siab dav yuav tsum tau ua raws li cov yam ntxwv xws li qhov loj ntawm qhov molded, cov txheej txheem complexity, kev siv ib puag ncig, thiab kev xav tau ib puag ncig. Qhov yooj yim ntawm lub tshuab nqus tsev tsim cov txheej txheem thiab qhov zoo ntawm cov plaub hom ntawv no ua ke sib koom ua ke, sib koom ua ke txhawb nqa ntau yam kev xav tau los ntawm kev ntim khoom ib txwm mus rau siab -kev tsim khoom kawg, thiab txhawb kev txhim kho kev lag luam plastics.
