Cov yam ntxwv thiab kev faib tawm ntawm PP Blister ntim cov ntaub ntawv

PP yog cov ntaub ntawv siv dav hauv lub tshuab nqus tsev, nrog lub npe Suav ntawm "polypropylene", thiab nws cov ntaub ntawv siv yog HIPS. Nyob rau hauv cov txheej txheem ntawm lub tshuab nqus tsev tsim, nws yog ib qho tsim nyog yuav tau hloov kho kom tau raws li qhov xav tau ntawm ntau lub tshuab nqus tsev tsim cov khoom ntim. PP cov ntaub ntawv muaj cov thermal expansion coefficient siab heev, thiab tshwj tsis yog rau cov ntaub ntawv sau, PP muaj qhov cuam tshuam loj heev rau deform thiab tus nqi ua haujlwm siab (txog 2.1%, nyob ntawm qhov kub thiab txias). Nws cov crystal melting point yog 158-165 degrees Celsius, thiab nws lub sij hawm siv kub ntau yog 0-110 degrees Celsius. Cov yam ntxwv ntawm cov khoom siv PP ua rau nws nyuaj rau kev ua haujlwm hauv thermoforming, thiab lub tshuab nqus tsev tsim ntim kev lag luam jokingly hu nws cov khoom PP mischievous.
Cov khoom siv PP feem ntau yog siv rau hauv lub tshuab nqus tsev ntim khoom noj, thiab tseem muaj ntau hom. Raws li qhov xav tau, ntau yam khoom siv PP tuaj yeem hloov kho thiab tsim tawm. Hais txog xim, lawv tuaj yeem muab faib ua PP natural xim, PP natural xim pob tshab, PP siab transparency cov ntaub ntawv, thiab ntau yam xim. Cov yam ntxwv ntawm txhua yam khoom sib txawv, yog li cov khoom siv kuj sib txawv.
Cov yam ntxwv dav dav ntawm cov khoom siv PP yog tias nws tsuas tuaj yeem tiv taus qhov kub thiab txias, yog li cov khoom tuaj yeem tso rau hauv tub yees thiab feem ntau yog siv rau hauv khw muag khoom ntim khoom noj. Cov xim tuaj yeem yog PP ntuj dawb lossis ua rau lwm yam xim raws li xav tau.
Cov khoom siv pob tshab, tseem hu ua semi pob tshab PP khoom, muaj ob yam ntxwv ntawm qhov kub thiab txias tsis kam, tab sis tsis muaj qhov zoo tagnrho, yog li nws tsuas yog tsim nyog rau cov khoom lag luam nrog cov kev cai dav dav rau qhov kub thiab txias. Qhov kev faib ua feem: yas ntim ntawm dumplings, nplej dumpling, thiab lwm yam. Cov khoom siv no tsis tuaj yeem lees txais kev kuaj nkag ntawm micro boilers.
Cov khoom siv pob tshab PP muaj qhov ua tau zoo rau ob qho tib si kub thiab qis, nrog rau cov khoom nplaum zoo, ua rau nws tsim nyog rau kev sib khi thiab kub kub hauv micro boilers, tab sis nws tus nqi kuj siab dua.
