Cov khoom siv pp li cas?
PP yog luv luv rau polypropylene, ib thermoplicity polymer ua los ntawm cov polymerisation ntawm propylene monomer. Raws li ib qho tseem ceeb yas khoom siv, PP muaj ntau cov kev siv hauv lub neej txhua hnub thiab kev lag luam ntau lawm. Hauv tsab xov xwm no, peb yuav tshawb xyuas kom meej txog cov khoom siv pp dab tsi yog, nrog rau nws cov yam ntxwv, siv thiab zoo.
Cov yam ntxwv yooj yim ntawm pp khoom
PP cov khoom siv muaj cov khoom siv lub cev thiab tshuaj lom neeg zoo. Nws qhov ntom ntom yog tsawg, tsuas yog hais txog 0.9 g / cmÃ, yog nws muaj cov cua sov tsis kam, tuaj yeem siv nyob rau hauv kub siab dua 100 ° C tsis muaj deformation , thiab feem ntau ntawm cov kua qaub, alkalis thiab cov kuab tshuaj organic muaj zoo corrosion tsis kam. Vim tias cov txiaj ntsig zoo no, pp khoom tau dhau los ua cov khoom siv zoo tagnrho hauv ntau thaj teb.
Kev faib tawm thiab hloov kho ntawm cov ntaub ntawv sau
PP cov ntaub ntawv tuaj yeem raug faib ua ob pawg tseemceeb, homopolymer polypropylene thiab copolymer polypropylene, nyob ntawm lawv cov qauv molecular thiab cov khoom. Homopoler polypropylene muaj siab nruj thiab lub zog rau cov khoom siv vinyl, thiab feem ntau yog siv nyob rau hauv cov ntawv thov uas yuav tsum tau cuam tshuam zoo dua.PP tseem tuaj yeem Tau hloov los ntawm kev ntxiv cov khob fitters, cov nplaim hluav taws xob, lossis nplaim taws retardants los txhim kho nws cov khoom siv lub cev thiab kub ua kom tau raws li cov kev xav tau ntawm cov ntawv thov. PP kuj tseem tuaj yeem hloov kho los ntawm kev ntxiv khob fibers lossis nplaim taws lossis nplaim taws ua kom nws cov khoom siv lub cev thiab kub tsis kam ua kom tau ntau yam kev siv.
Daim ntawv thov cov khoom ntawm pp khoom
PP cov khoom tuaj yeem pom nyob txhua qhov chaw hauv lub neej, thiab lawv cov ntawv thov npog cov ntaub ntawv ntim thiab hauv tsev cov khoom lag luam rau kev lag luam tsheb thiab khoom siv kho mob. Hauv kev ntim khoom, pp khoom siv tau dav nyob rau hauv kev tsim cov khoom noj khoom haus, cov duab haus thiab lwm yam khoom, tsis muaj tshuaj lom thiab hauv txoj kab nrog cov qauv kev nyab xeeb. Hauv tsev cov khoom, pp khoom siv yog feem ntau siv los ua cov thawv ntim khoom, cov khaub ncaws ntxhua khaub ncaws, rooj tog zaum thiab lwm yam. Vim nws cov cua sov zoo thiab tshuaj lom neeg tiv thaiv, PP tseem siv nyob rau hauv lub tsheb kho mob los ua pob tw, thiab roj teeb
Ib puag ncig tus phooj ywg thiab muaj kev cia siab
Nyob rau hauv xyoo tsis ntev los no, raws li ib puag ncig kev paub tau nce, pp cov ntaub ntawv tau txais ntau dua kev saib xyuas vim lawv cov kev rov ua dua tshiab thiab qis dua ib puag ncig thiab qis dua ib puag ncig. PP cov ntaub ntawv tuaj yeem raug rov ua dua los ntawm kev rov ua dua tshiab tom qab muab pov tseg, txo cov pa phem rau ib puag ncig. Txawm hais tias pp khoom tsis yog biodegradable, nws qhov kev cuam tshuam ib puag ncig tuaj yeem txo kom tau txo kom dhau los ntawm kev tswj hwm pov tseg thiab rov ua dua tshiab. Yog li, pp khoom yog suav hais tias yog ib tug phooj ywg zoo thiab muaj cov khoom siv yas ua kom ruaj khov.
Lub ntsiab
PP cov khoom siv yog cov khoom siv yas ntau yam nrog ntau cov ntawv thov. Nws qis ntom ntom, cov tshuaj kub tsis kam, tshuaj lom neeg thiab rov ua dua tshiab ua rau nws ib qho ntawm cov khoom tsis tseem ceeb hauv kev lag luam niaj hnub thiab lub neej niaj hnub. Los ntawm kev nkag siab dab tsi pp khoom yog thiab nws cov cheeb tsam ntawm daim ntawv thov, koj tuaj yeem zoo siv cov txiaj ntsig no ntawm cov khoom siv no los muab kev xaiv zoo rau kev tsim thiab ntau lawm cov khoom lag luam.
