Amasu okusebenza nezibonelo zempushana yerabha eshisiwe ekuguqulweni kwe-PVC
Impushana yenjoloba eyenziwe nge-vulcanized yenziwa ngokuchoboza irabha yemfucuza ngezindlela zemishini, izindlela zokuqandisa nezinye izindlela. Kuyimpushana enokunwebeka kwerabha futhi ingasetshenziswa embonini yepulasitiki. Ingaxutshwa nganoma yiliphi inani kumapulasitiki futhi igaywe ibe yimpushana yerabha ukuze kuqiniswe amapulasitiki ngamapulasitiki njengento eyisisekelo. I-Polyvinyl chloride ingenye yazo. Ekukhiqizeni kwangempela, i-polyvinyl chloride eqinisiwe futhi ishintshwe nge-raber powder evuvuziwe ingacutshungulwa ibe yimikhiqizo ehlukahlukene ngokusebenzisa ukubunjwa, i-laminating, i-calendering, ukubunjwa komjovo, i-extrusion, njll. Impushana yerabha yeTire kanye ne-nitrile rubber powder ku-vulcanized rubber powder yizinto ezivame ukusetshenziswa zokuguqulwa kwe-PVC.
- Izindlela zokufaka isicelo se-powder yerabha yamasondo ekuguqulweni kwe-PVC
Impushana yerabha yethaya ecutshungulwa emathayini alahlwayo ivame ukusetshenziswa njengesigaba esihlakazekile lapho kulungiswa i-PVC. Uma kuphezulu ukucoleka, kuba ngcono ukumelana komthelela we-PVC/impuphu yerabha yamasondo. Kunconywa ukusebenzisa i-rubber powder yamathayi enobuhle obungama-80 mesh noma ngaphezulu. Amandla omthelela wento ye-PVC akhombisa inkambiso yokuqala ekhuphuka ngokushesha, bese ikhuphuka kancane, futhi ekugcineni yehle kakhulu ngokunyuka kokusetshenziswa kwempuphu yerabha yesondo. Ekukhiqizeni kwangempela, lapho inani le-powder yerabha yesondo elisetshenzisiwe lilinganiselwa ku-10% yenani lempahla ye-PVC esetshenzisiwe, ukusebenza komthelela wezinto eziguquliwe ze-PVC zenjoloba yiyona engcono kakhulu.
- Amasu okusebenza we-nitrile rubber powder ekuguqulweni kwe-PVC
I-Nitrile rubber powder iyisisetshenziswa esivame ukusetshenziswa esiqinisayo nesishintshayo se-polyvinyl chloride. Usayizi wezinhlayiyana kanye nomthamo we-nitrile rubber powder kunemiphumela elandelayo ezintweni eziguquliwe ze-PVC: Ukuqina kwe-nitrile rubber powder 2ELYY92WFM, kuba ngcono umphumela oqinile ezintweni ze-PVC. Kunconywa ukusebenzisa imikhiqizo enosayizi we-mesh we-60 noma ngaphezulu. Ngokukhula komthamo wempuphu yerabha ye-nitrile, amandla womthelela we-PVC akhombisa inkambiso yokuqala yokwehla kancane bese ikhula ngokushesha. Uma uqinisa futhi ulungisa izinto ze-PVC nge-nitrile rubber powder, kunconywa ukusebenzisa i-sulfur vulcanization.
- Isicelo Izibonelo ze-nitrile rubber Powder ekuguqulweni kwe-PVC
Lapho ulungiselela izinto zokuvikela ezinegwebu ngokuhlanganisa irabha ye-nitrile ne-PVC, impushana yerabha ye-nitrile ingasetshenziselwa ukuguqulwa. Ekukhiqizweni kwangempela, ukucoleka nokungcola kokuqukethwe kwerabha ye-nitrile kungathinta ukubumbana, ukumelana nokuphefumula komoya kanye nokumuncwa kwamanzi kwezinto zokufaka amagwebu. Kunconywa ukusebenzisa i-nitrile rubber powder enobukhulu obungamameshi obungama-80 noma ngaphezulu, engahlakazwa ngokulinganayo emixubeni yenjoloba-yepulasitiki futhi cishe ayinawo umthelela emandleni emishini, ukubumbana, ukumelana komoya nokumuncwa kwamanzi ezinto ezinegwebu.
Embonini yepulasitiki, impushana yenjoloba eshisiwe ingaxutshwa namapulasitiki ahlukahlukene njenge-polyethylene, i-polyvinyl chloride, i-polypropylene, i-polystyrene, nama-thermoplastic elastomers ukuze kuthuthukiswe ukuqina kwezinto zepulasitiki futhi kuthuthukise ukumelana kwazo nomthelela. Uma wengeza impushana yerabha eshisiwe ku-polyvinyl chloride, inani elilinganiselwe le-compatibilizer lingasetshenziswa futhi ukulungisa impushana yerabha. Ngemuva kwalokho, ingahlanganiswa ne-PVC ukuze kube nomphumela oqinile wokuqina. Ngokuzayo, umhleli uzoqhubeka nokwabelana nawe ngezinye izinhlelo zokusebenza zempushana yerabha engcolile embonini yepulasitiki.
