PVC compound yog dab tsi?
Cov tshuaj sib xyaw PVC yog ua los ntawm kev sib xyaw ua ke ntawm PVC polymer RESIN thiab cov khoom ntxiv uas muab cov qauv tsim nyog rau kev siv kawg (Cov kav dej lossis Cov Qauv Rigid lossis Cov Qauv Yooj Yim lossis Cov Ntawv). Cov tshuaj sib xyaw no yog tsim los ntawm kev sib xyaw ua ke cov khoom xyaw, uas tom qab ntawd hloov mus ua cov khoom "gelled" nyob rau hauv kev cuam tshuam ntawm cua sov thiab lub zog shear. Nyob ntawm hom PVC thiab cov khoom ntxiv, cov tshuaj sib xyaw ua ntej gelation tuaj yeem yog cov hmoov ntws dawb (hu ua kev sib xyaw qhuav) lossis cov kua hauv daim ntawv ntawm cov tshuaj nplaum lossis cov kua. Cov tshuaj sib xyaw PVC thaum tsim, siv cov yas, mus rau hauv cov ntaub ntawv yooj ywm, feem ntau hu ua PVC-P. Cov tshuaj sib xyaw PVC thaum tsim tsis muaj yas rau cov ntawv thov nruj yog xaiv PVC-U. PVC Compounding tuaj yeem sau ua raws li hauv qab no: Cov khoom siv PVC nruj ... -
Qhov txawv ntawm BOPP, OPP thiab PP hnab.
Cov lag luam zaub mov feem ntau siv cov yas ntim khoom BOPP. Cov hnab BOPP yooj yim luam tawm, txheej thiab laminate uas ua rau lawv haum rau kev ntim cov khoom xws li cov khoom tshiab, khoom qab zib thiab khoom noj txom ncauj. Nrog rau BOPP, OPP, thiab PP hnab kuj siv rau kev ntim khoom. Polypropylene yog ib qho polymer feem ntau ntawm peb yam siv rau kev tsim cov hnab. OPP sawv cev rau Oriented Polypropylene, BOPP sawv cev rau Biaxially Oriented Polypropylene thiab PP sawv cev rau Polypropylene. Tag nrho peb yam sib txawv hauv lawv cov qauv tsim. Polypropylene tseem hu ua polypropene yog ib qho thermoplastic semi-crystalline polymer. Nws yog tawv, muaj zog thiab muaj kev tiv taus kev cuam tshuam siab. Cov hnab sawv ntsug, cov hnab spout thiab cov hnab ziplock yog ua los ntawm polypropylene. Nws nyuaj heev rau kev sib txawv ntawm OPP, BOPP thiab PP plas... -
Kev Tshawb Fawb Txog Kev Siv Lub Teeb Pom Kev Zoo (PLA) Hauv LED Teeb Pom Kev Zoo.
Cov kws tshawb fawb los ntawm lub teb chaws Yelemees thiab Netherlands tab tom tshawb nrhiav cov ntaub ntawv PLA tshiab uas zoo rau ib puag ncig. Lub hom phiaj yog los tsim cov ntaub ntawv ruaj khov rau kev siv kho qhov muag xws li lub teeb tsheb, lub lens, cov yas uas cuam tshuam lossis cov lus qhia teeb. Tam sim no, cov khoom no feem ntau yog ua los ntawm polycarbonate lossis PMMA. Cov kws tshawb fawb xav nrhiav cov yas bio-based los ua lub teeb tsheb. Nws hloov tawm tias polylactic acid yog cov khoom siv tsim nyog. Los ntawm txoj kev no, cov kws tshawb fawb tau daws ntau yam teeb meem uas cov yas ib txwm ntsib: thawj zaug, tig lawv txoj kev mloog mus rau cov peev txheej rov ua dua tshiab tuaj yeem txo qhov kev nyuaj siab los ntawm roj av rau kev lag luam yas; qhov thib ob, nws tuaj yeem txo cov pa roj carbon dioxide; qhov thib peb, qhov no cuam tshuam txog kev xav txog tag nrho cov khoom siv lub neej c... -
