Kev cuam tshuam cuam tshuam ua tau lub luag haujlwm tseem ceeb hauv kev tsim thiab xaiv polymers siv nyob rau hauv cov ntawv thov tseem ceeb. Cov kev siv no los ntawm Bumpers Tsheb thiab cov iav kev nyab xeeb rau cov cuab yeej siv hluav taws xob thiab cov khoom siv kho mob. Raws li kev lag luam nrhiav kev sib tw sib txawv, muaj zog dua, thiab ntau dua ib puag ncig cov ntaub ntawv ntawm kev nce qib yog hloov zuj zus, thiab {{{3} {tus qauv tsim.
Ib qho yas cov kev cuam tshuam kuj yog hais txog nws lub peev xwm ua kom muaj kev cuam tshuam sai sai uas tsis muaj deforming. Los ntawm lawv cov xwm txheej, cov khoom siv yas tuaj yeem ua piv txwv sib txawv ntawm cov kev cuam tshuam. Qee qhov plastics yog inherently brittle, thaum lwm tus yog coorile thiab tuaj yeem nqus tau qhov tseem ceeb cuam tshuam rau lub zog. Qhov tseem ceeb, kev cuam tshuam- tiv taus plastics yog tsim kom muaj kev sib npaug lub zog, hloov tau yooj yim, thiab kav ntev. Qhov no ua rau lawv tiv thaiv kev cuam tshuam cuam tshuam thiab muab kev ua tau zoo.
Kev ua tiav kev cuam tshuam ntawm siab tsis kam nyob rau hauv cov plastics yuav tsum ua tib zoo tswj ntawm ntau yam:
● Cov qauv molecular ntawm cov polymer
Tus muaj nyob ntawm Copolymers
Address Ad Ntxiv ntawm kev txhawb nqa lossis hloov kho
● Ib puag ncig cov neeg (piv txwv li, ntsuas kub)
Siab - kev cuam tshuam polystyrene (hips)
High {{0} Txoj Kev Cuam Tshuam Muaj Zog Yog Tus Qauv Kho Ntawm Polystyrene nrog roj hmab ntxiv rau nws cov kev cuam tshuam tsis kam. Nws yog lub npe hu rau nws cov kev cuam tshuam zoo lub zog, rigidity, thiab yooj yim ntawm kev ua. Nws tseem raug nqi -} Zoo thiab yooj yim rau thermoform. Txawm li cas los xij, nws cov cua sov tsis kam thiab UV ruaj khov yog txwv. Nws cov ntawv thov suav nrog ntim, tsev nyob hauv tsev, khoom ua si, thiab cov khoom lag luam sab hauv.
Polycarbonate (PC)
Cov khoom pov thawj polycarbonate tsis tshua muaj kev cuam tshuam tseem ceeb, txawm tias thaum kub tsawg. Nws tshwj xeeb cov qauv molecular tshwj xeeb ntev, hloov cov saw hlau yooj yim uas deform yooj yim thiab nqus kev cuam tshuam lub zog. Nws tseem muaj lub npe rau nws cov kev pom tseeb kho qhov muag, seem ruaj khov, thiab siab - kub tsis kam. Feem ntau hais lus, pc ua yeeb yam zoo cuam tshuam tsis kam mus. Txawm li cas los xij, nws yog cov khoom siv kim dua. Nws yog siv hauv kev nyab xeeb tsom iav, cov chaw tsheb, thiab cov khoom siv hluav taws xob.
Acrylonitrile Butadiene STyrene (ABS)
Acrylonitrile Butadiene STyrene muaj qhov sib txawv styrene - acrylonitrile matrix nrog cov roj hmab disadiene tawm. Cov roj hmab hais ua raws li kev cuam tshuam hloov kho, nqus lub zog thiab tiv thaiv tawg. ABS muaj kev sib npaug zoo nruab nrab ntawm cuam tshuam kev cuam tshuam, tsis sib xws, thiab txheej txheem. Nws yog tus nqi qis -} zoo muab piv rau PC thiab muaj qhov zoo ua tiav. Nws tseem muaj cov tshuaj zoo tsis kam. Nws yog siv hauv kev lag luam sab hauv cov chaw, tshuab hluav taws xob, thiab cov neeg siv khoom.
Polypropylene (pp)
Qhov cuam tshuam tsis kam ntawm polypropylene txawv nyob ntawm nws cov qauv. PP copolymers muaj kev cuam tshuam siab dua tsis yog homopolers. Nws yog paub txog nws cov tshuaj tsis kam thiab nkees ua yeeb yam. Nws tuaj yeem ua nkig ntawm tsawg kub. Nws yog siv rau hauv cov ntawv thov xws li pob tsheb pob tsheb, ntim, thiab khoom siv muaj.
Polyethylene (PE)
Polyethylene cov khoom ua pov thawj zoo heev tshuaj lom neeg tiv thaiv thiab tsawg- kub hloov. Hauv qee hom, PE tuaj yeem muaj kev cuam tshuam ntau heev. Siab - ntom polyethylene (HDPE) muaj kev cuam tshuam zoo, tshwj xeeb tshaj yog cov ntawv tuab. Tsawg -} ceev polyethylene (ldpe) thiab linear qis {} ldlpe muaj kev cuam tshuam nrog kev cuam tshuam zoo dua li LDPE. Nws yog feem ntau siv nyob rau hauv ntim, kav dej, thiab ntim.
Qhov cuam tshuam tsis kam ntawm cov plastics coj cov txiaj ntsig nram no:
● Lawv muab kev tiv thaiv tseem ceeb hauv kev thov yuav raug cuam tshuam, txo qis kev pheej hmoo ntawm kev raug mob thiab kev puas tsuaj.
● Lawv tuaj yeem tiv thaiv huab cua huab cua, tshuaj lom neeg, thiab lwm txoj kev ntxhov siab ib puag ncig, ua rau lawv tsim nyog rau kev siv hauv cov chaw hnyav.
● Lawv tuaj yeem ua pwm rau hauv ntau cov duab thiab cov ntaub ntawv, enabling cov khoom tsim tshiab.
● Lawv muaj lub zog muaj zog - rau - qhov hnyav sib piv, txhawb nqa cov khoom lag luam sib npaug thiab nce ntxiv.
● Lawv txuas ntxiv lub neej ntawm cov khoom los ntawm kev hnav ris tsho, thiab kua muag thiab cuam tshuam. Qhov no txo qhov xav tau kev hloov ntau zaus, txuag cov nqi thiab cov peev txheej.
● Ntau ntau yam kev cuam tshuam- tiv taus plastics yog yooj yim rau cov nqi.
● Lawv pab txhim kho cov roj tsheb ua haujlwm thiab txo cov nqi tsheb thauj mus los.
