Imicu yokutywina ye-PVC iye yaba yintandokazi yocango lwentsimbi yeplastiki kunye nemicu yokutywina yefestile kuba ayiqhekeki kwaye kulula ukuyidibanisa.Kodwa kuphela iminyaka emi-2-3, ingxaki yavela.Ukwahlula iiplastiki zePVC, ingxaki enzima yoshishino lwamazwe ngamazwe, ibonakaliswe ngokucacileyo kwimicu yokutywina ye-PVC.
Ngenxa yokuhlukana kwe-plasticizer, iphrofayili ingcoliswa ngumgca we-rubber, ubude bufutshane, icandelo eliphukileyo lifutshane, kwaye iingxaki zokutywinwa okungahambi kakuhle zininzi.Nangona kunjalo, ukusetyenzwa kweworkshop encinci yaseTshayina, ukuncitshiswa kweendleko zesiTshayina, kunye nokhuphiswano lwamaTshayina ngexabiso eliphantsi ngomnyango kunye nabavelisi befestile yokutywina kuye kwakhokelela ekusetyenzisweni kweeplasticizers ezineziphene kunye nePVC esetyenzisiweyo, eye yandisa iingxaki zalo lonke ixesha. ishishini strip lokutywina.Isiphelo sePVC sokutywina siqala ukubonakala.
Imichilo yokutywina ye-EPDM EPDM Ekuqaleni kwe-2000, ilizwe lakhupha umyalelo woluntu wokukhawulela ukusetyenziswa kwe-polyvinyl chloride ye-PVC yokutywina imicu, kwaye yakhuthaza ukusetyenziswa kwe-EPDM EPDM imicu yokutywina kunye nemicu yokutywina ye-silicone ye-MVQ.Umgca wokutywina we-EPDM, umtya wokutywina womgangatho ophezulu osetyenziswa kwiimoto kunye noololiwe, ekugqibeleni wamkelwe lishishini lokwakha.
Enyanisweni, yayisetyenziswa ngokubanzi kwishishini lomnyango kunye nefestile emva kwe-2002. Ngelo xesha, iingcango kunye neefestile zangena ngokuthe ngcembe kwixesha le-aluminium alloys ephukileyo.I-EPDM iye yafana nemigca yokutywina yomgangatho ophezulu ngenxa yeempawu zayo eziphezulu zomzimba kunye nokumelana nokuguga okulungileyo.Ngo-2011, echatshazelwa yi-oyile yamazwe ngamazwe kunye nezinye izinto, ixabiso le-ethylene propylene lenyuka, kwaye ubusika be-EPDM ukutywinwa kwemicu beza, ngoko ke ubulumko baseTshayina beza, irabha ebuyiselweyo yaqala ukusetyenziswa ngobuninzi, kwaye yonke imarike yomgca wokutywina yayingaphakathi. isiphithiphithi.Amatywina amahle kunzima ukufumana.Umcu wokutywina womnyango kunye nefestile@门Window气气调板厂家Isithili esithile eTshayina sisiseko semicu yokutywina yasekhaya, kwaye malunga ne 70% yemicu yokutywina yesakhiwo yase China ye EPDM ivela kule dolophu.Kukho umphathi kumsebenzi ofanayo kule dolophu, kwaye i-70% yelizwe lokutywina i-ethylene-propylene strips ivela kuthi.
Umtya wokutywina werabha ye-silicone ayiyonto yamva nje yokutywina, kodwa akunjalo.Irabha yeSilicone inembali yamashumi eminyaka eTshayina.Abavelisi bemigca yokutywina yocango kunye neefestile ngokwenene zezona zithandwayo zerabha kule minyaka imbalwa idlulileyo, kwaye zibuthathaka kakhulu.Kwiminyaka yakutshanje, iindleko ziye zancipha ngokuthe ngcembe, kwaye ziye zasetyenziswa ngokuthe ngcembe ekwakheni amatywina.
Xa kuthelekiswa nerabha ye-ethylene-propylene, inzuzo yerabha ye-silicone yokutywinwa kukuba inokuncipha okungcono kunye nokusebenza kwe-deformation kunerabha ye-ethylene-propylene, ngoko ke ukusebenza kokutywinwa kungcono, kwaye ukusuka kumgaqo wokulinganisa ubushushu bexesha, irabha ye-silicone inokumelana. amaqondo obushushu ukuya kuthi ga kwi-300 ° C, kwaye iyamelana nerabha ethylene-propylene.Irabha ikwiqondo eliphezulu le-180°C.Ngaphantsi kobushushu obufanayo, ubomi berabha ye-silicone buphindwe kabini kunerabha ye-ethylene propylene, kwaye ubomi benkonzo bude.Kwaye ine-inertia ye-physiological egqwesileyo, ayinayo ityhefu, ayinancasa, irabha ye-silicone nayo inokumelana nobushushu obubalaseleyo, ukumelana nokubanda, iipropathi ze-dielectric, ukuxhathisa kwe-ozone kunye nokumelana nokuguga komkhathi kunye neminye imisebenzi, umsebenzi obalaseleyo werabha ye-silicone kukusetyenziswa kobushushu obubanzi, unokusebenzisa ucango kunye nomvelisi wefestile yokutywina ixesha elide kwi -60 ° C (okanye ubushushu obuphantsi) ukuya +250 ° C (okanye ubushushu obuphezulu).Ke irabha ye-silicone lukhetho olufanelekileyo lokwakha izitywina kwixesha langoku.
