Chirevo chekuvanzika: Kuvanzika kwako kwakakosha kwazvo kwatiri
PP (polypropylene) uye pe (polyethyle) zvinhu zviviri zvepapurasitiki izvo zvinosiyana mumamiriro avo emakemikari, zvivakwa zvemuviri, kupisa, uye huwandu hwenzvimbo:
Chemical composition : Chikamu chikuru chePP chiri polypropylene, nepo chikuru chikamu chePe chiri polyethylene.
Zvivakwa zvemuviri: PP kazhinji ine yakakwira yekunyungudika pfungwa uye yekunyungudza tembiricha pane iyo, saka dentity yeiyo inowanzove mune yegumi ye1.91 ~ 0.96g / cm³, nepo density ye pp iri mune huwandu hwe 0.90 ~ 0.91g / cm³, cm³ uye kuomarara uye kuomarara kwePP kazhinji kwakakwirira kune pe, asi kuomarara kunorambidza kuderera kupisa.
Kupisa kupokana: Pe kune zviri nani kupisa kupesana, kunogona kushandiswa zvakajairika munzvimbo dze -60 PP's High Tembiricha iri nani zvakanyanya, inogona kushandiswa zvinowanzoitika pamadhigirii zana Celsius, uye inogona kutopiswa mumicrowave oven.
Chiyero chekushandisa:
Pe inowanzoshandiswa mukugadzira mafirimu, midziyo, mapepa, tambo insulation uye zvimwe zvigadzirwa zvinoda kushanduka uye kutonhora kuramba. Uye PP inowanzoshandiswa mugadziri ye pombi, hutsanana, midziyo yokushambadzira, tubing
Kuchinjika: Pe zvinhu zvine musoro zvakanyorova, zviri nyore kwazvo kushatirisa mushure mekunyungudutswa; Nepo PP zvinyorwa zvakaoma, zvishoma zvinoshanduka.
Kuparadzaniswa Kwemamiriro ekunze: Pe ine yepamusoro mamiriro ekunze, nepo PP ine kuderera mamiriro ekunze.
Kuchengetedza: PE uye PP haina chepfu, chemakemikari yakagadzikana uye nyore kuumbwa uye maitiro.
Zvakazara, pp uye pe ine yavo zvakanakira maererano nekuita, uye sarudzo yeiyo zvinyorwa zvekushandisa zvinoenderana nezvinodiwa chaizvo.
Tiri kukupa kuenzanisa nhasi kwemisiyano pakati pePP uye PE ZVINONYANYA ZVINOSHANDISA ZVAKAWANDA.
Pe ndizvo zvatinowanzo kureva nezve polyethylyer.lolook padhuze chena;
Pp iri polypropylene, izvi zviviri zvigadzirwa zvichienzaniswa nezvakanaka nezvakanaka zvacho, chimiro chakakurumbira ndechekuti simba rekukotama rakakwira kupfuura pe, kureva kuti isu tiri munguva dzinoverengeka kana kukotama kwe Zvinyorwa zvePP hazvisi nyore kushomeka, uye Simba rePP rine simba uye simba rekumanikidza rakasimba, rakavakirwa pane zvePP zvinyorwa, kusarudzwa kwePP zvinyorwa, rutsigiro runogona kuitwa kuti riite rakareruka uye rakaonda.
Kuenzaniswa nePP zvinyorwa zvePP ndeyekupisa kwePP kwakakwirira, zvichikonzera kuumbwa kwayo kwakanyanya kuoma pane pepa kune pendi pane pe, mukutambira kwakasimba, kana kutopwanya, isu Vari mukusarudzwa kwezvinhu zvekutsigira, isu tinofanirwa kuteerera kune rutsigiro rwokugadzira zano rekusarudza zvinhu zvakakodzera zvakanyanya.
