PP khoom yog dab tsi?
PP luv luv rau Polypropylene, thermoplastic polymer ua los ntawm polymerization ntawm propylene monomer. Raws li cov khoom siv yas tseem ceeb, PP muaj ntau yam kev siv hauv lub neej txhua hnub thiab kev tsim khoom lag luam. Hauv tsab xov xwm no, peb yuav txheeb xyuas kom meej tias cov khoom siv PP yog dab tsi, nrog rau nws cov yam ntxwv, kev siv thiab qhov zoo.
Cov yam ntxwv ntawm cov khoom siv PP
PP cov khoom muaj lub cev zoo thiab tshuaj lom neeg. Nws qhov ceev yog tsawg, tsuas yog hais txog 0.9 g / cm³, yog qhov qis tshaj plaws ntawm cov yas, yog li nws muaj qhov hnyav dua. PP cov khoom siv hluav taws xob thiab tshuaj lom neeg kuj zoo heev, tuaj yeem siv rau qhov kub siab tshaj 100 ° C yam tsis muaj deformation. , thiab feem ntau ntawm cov acids, alkalis thiab organic solvents muaj corrosion kuj zoo. Vim tias qhov zoo no, cov khoom siv PP tau dhau los ua cov khoom siv zoo tshaj plaws hauv ntau qhov chaw.
Kev faib tawm thiab kev hloov kho cov ntaub ntawv PP
PP cov ntaub ntawv tuaj yeem muab faib ua ob pawg tseem ceeb, homopolymer polypropylene thiab copolymer polypropylene, nyob ntawm lawv cov qauv molecular thiab cov khoom. Homopolymer polypropylene muaj rigidity siab thiab lub zog, ua rau nws haum rau cov khoom uas yuav tsum tau hardness siab, thaum copolymer polypropylene muaj zoo toughness thiab muaj zog muaj zog vim hais tias ntawm cov kev taw qhia ntawm vinyl units, thiab feem ntau yog siv nyob rau hauv daim ntawv thov uas yuav tsum tau zoo dua tej yam kuj.PP kuj. tau hloov kho los ntawm kev ntxiv cov iav fibers, cov ntxhia pob zeb, los yog cov nplaim hluav taws kub hnyiab los txhim kho nws lub cev thiab cov cua sov, kom ua tau raws li qhov xav tau ntawm ntau yam kev siv. PP kuj tseem tuaj yeem hloov kho los ntawm kev ntxiv cov iav fibers lossis cov ntxhia pob zeb los yog cov nplaim hluav taws kub hnyiab los txhim kho nws lub cev thiab tiv thaiv tshav kub kom tau raws li ntau yam kev siv.
Kev siv cov khoom siv PP
PP cov ntaub ntawv tuaj yeem pom nyob txhua qhov chaw hauv lub neej, thiab lawv daim ntawv thov npog ntau qhov chaw, los ntawm cov khoom ntim thiab cov khoom siv hauv tsev mus rau kev lag luam tsheb thiab khoom siv kho mob. Hauv kev ntim khoom, cov khoom siv PP yog siv dav hauv kev tsim cov thawv ntim khoom noj, lub raj mis dej haus, cov yeeb yaj kiab thiab lwm yam khoom, uas tau nyiam vim tias lawv tsis muaj tshuaj lom, tsis qab thiab ua raws li cov qauv kev nyab xeeb khoom noj. Hauv cov khoom siv hauv tsev, cov khoom siv PP feem ntau yog siv los ua cov thawv ntim khoom, khaub ncaws pob tawb, rooj tog zaum thiab lwm yam. Vim nws cov cua kub zoo thiab tshuaj lom neeg tsis kam, PP kuj tseem siv rau hauv kev lag luam tsheb los ua cov bumpers, dashboards thiab roj teeb rooj, thiab lwm yam. PP kuj tau siv dav hauv kev kho mob, xws li cov koob txhaj tshuaj pov tseg, lub raj mis infusion thiab cov cuab yeej phais.
Environmentally Friendly thiab Sustainable
Nyob rau hauv xyoo tas los no, raws li kev paub txog ib puag ncig tau nce, PP cov ntaub ntawv tau txais kev saib xyuas ntau dua vim lawv cov khoom siv rov ua dua tshiab thiab kev cuam tshuam ib puag ncig qis. PP cov ntaub ntawv tuaj yeem rov ua dua los ntawm kev rov ua dua tom qab pov tseg, txo cov pa phem rau ib puag ncig. Txawm hais tias cov khoom siv PP tsis yog biodegradable, nws qhov kev cuam tshuam ib puag ncig tuaj yeem txo tau zoo los ntawm kev tswj xyuas pov tseg thiab rov ua dua tshiab. Yog li ntawd, PP cov khoom yog suav hais tias yog ib qho kev sib raug zoo ib puag ncig thiab cov khoom siv yas ruaj khov.
Cov ntsiab lus
Cov khoom siv PP yog cov khoom siv yas uas muaj ntau yam nrog ntau yam kev siv. 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 txog cov khoom siv PP yog dab tsi thiab nws thaj chaw ntawm daim ntawv thov, koj tuaj yeem siv qhov zoo ntawm cov khoom siv no los muab kev xaiv txhim khu kev qha rau kev tsim thiab tsim khoom ntawm txhua hom khoom.
