Izinzuzo kanye nobubi bokusebenza komugqa wokufaka uphawu kuthinta ukungangeni komoya, ukumelana namanzi, ukulahlekelwa ukushisa nezinye izinkomba zokusebenza ezibalulekile zeminyango namafasitela eminyango yesakhiwo namafasitela ngezinga elikhulu, kanye nokuqina kweminyango kanye amafasitela.Ngenxa yalesi sizathu, izwe liye lakha indinganiso kazwelonke ye-GB12002-89 "Plastic door and window seal" isikhathi eside ukuze kumiswe ukukhiqizwa nokuhlolwa kwezimpawu.
Kodwa-ke, ikhwalithi yamanje kanye nentengo yezintambo zenjoloba kanye nepulasitiki yokuvala iminyango namafasitela emakethe yezinto zokwakha zidida kakhulu.Ibiza ngo-15,600 yuan ngethani, kodwa ishibhile ngo-6,000 yuan ngethani.Umehluko wentengo ucishe ube ngu-10,000 yuan, futhi ikhwalithi iyahluka kakhulu.Wonke umuntu uyazi ukuthi enzeni.Abakhiqizi abaningi bashilo ukuthi uphawu lwabo luwukusetshenziswa kwezinga likazwelonke le-GB12002-89, futhi umbiko wokuhlola ofanelekayo ungakhishwa yi-ejensi egunyaziwe.Ngokusho kwezimpawu zenjoloba zabakhiqizi abaziwayo inkampani yethu eyisebenzisayo njengamanje embonini, kanye namasampula emigqa yokuvala ekhishwe abakhiqizi, ukusebenza kokuguga komoya oshisayo wale phrojekthi kunomphumela omangazayo ekushiseni kwesisindo. inkomba: amasampula angaphezu kwe-10, empeleni, abekho abantu abafanelekile.
Ngokwezinga le-GB12002-89, into yokusebenza yokuguga komoya oshisayo yomugqa wokuvala kufanele ibe ngu-3% kunkomba yokuncipha kwesisindo sokushisa.Kodwa-ke, ukwehla kwesisindo sokushisa kwemiphumela yokuhlolwa kwangempela kungu-7.17% ~ 22.54%, okungaphezu kakhulu kobubanzi bezinga likazwelonke.
Kumapheshana okufaka uphawu anjalo, inani elikhulu lama-plasticizers aphansi abilayo noma ama-plasticizer substitutes ayengezwa kufomula.Lolu hlobo lophawu lusaguquguquka kakhulu enkathini entsha.Kodwa-ke, njengoba isikhathi sihamba, i-plasticizer iyaguquguquka kakhulu, ukunwebeka kokuvala kuhle, futhi kuyanciphisa futhi kubi, okuthinta ukusebenza kokuvala kusuka kumandla omthelela womnyango nefasitela, futhi kuthinta ukuqina komnyango nefasitela. umhlangano.
Ngaphezu kwalokho, okuqukethwe kwe-plasticizer ye-sealant kuphezulu kakhulu, futhi kuthintana nesenzakalo sokufuduka kwe-PVC resin ngesikhathi sokusetshenziswa kwe-plasticizer.Ibangela ukuthunjwa kozimele wabalandeli bendawo kanye nokuvuvukala.Okusho ukuthi: lapho uthintana nophawu endaweni yokubeka uphawu, kukhona ububanzi obubanzi futhi obuncane, obungaxubeki, ibala elimnyama, futhi umzimba omhlophe wenza umehluko oqinile, othinta kakhulu ukubonakala.Umbala ku-plasticizer kungenxa yokufuduka, nokuvuvukala kwendawo.(Izicabha ezishelelayo namafasitela awavezwa ngenxa yokuthintana namaphrofayili ezingxenye, futhi amaphrofayili anombala ngokwengxenye futhi avuvukele. Ngokuvamile, iminyango namafasitela avuliwe awanakubonwa lapho evuliwe. Uphawu namaphrofayili ahambisanayo ane uphelelwe amandla othintana naye.) Nakuba amaphrofayili Ombala wendawo kanye nokuvuvukala angenayo imiphumela emibi yokwehluleka kwamafreyimu namaphrofayili abalandeli, kodwa kuthinta kakhulu ukubukeka kweminyango namafasitela epulasitiki.Phela, lokhu kuyisici, emva kwakho konke, umphumela wesithombe seminyango namafasitela epulasitiki umpofu kakhulu.
Ukuze ulondoloze isithombe seminyango namafasitela epulasitiki futhi unakekele ukukhula okunempilo nokuqinile kwale mboni esafufusa, abakhiqizi be-strip strip kufanele bakhiqize izimpawu ezifanelekayo ngempela, futhi izitshalo zokuhlanganisa iminyango yepulasitiki namafasitela kufanele zisebenzise izimpawu ezifanelekayo ngempela zekhwalithi ephezulu.
