Abubuwa uku da aka saba amfani da su don bawul ɗin solenoid

1. NBR nitrile roba
Ana yin bawul ɗin na solenoid ta hanyar emulsion polymerization na butadiene da acrylonitrile. Nitrile roba an fi samar da shi ta hanyar ƙarancin polymerization emulsion emulsion. Ya na da kyau juriya mai, high lalacewa juriya, mai kyau zafi juriya, da karfi mannewa. Rashin hasararsa shine rashin juriya mara ƙarancin zafi, ƙarancin juriya na ozone, ƙarancin kaddarorin lantarki, da ƙarancin ƙarfi. Babban manufar bawul ɗin bawul: solenoid valve nitrile roba galibi ana amfani da shi don yin samfuran masu jurewa mai. Solenoid bawul kamar bututu masu jurewa mai, kaset, diaphragms na roba da manyan jakar mai ana yawan amfani da su don yin samfuran da aka ƙera mai, kamar O-zobba, hatimin mai, da fata. Hakanan ana amfani da kwano, diaphragms, bawuloli, bellows, da sauransu don yin zanen roba da sassan da ba sa iya jurewa.
2. EPDM EPDM (Ethylene-Propylene-Diene Monomer) solenoid bawul Babban fasalin EPDM shine mafi girman juriya ga hadawan abu da iskar shaka, ozone da lalata. Tunda EPDM na dangin polyolefin ne, yana da kyawawan kaddarorin vulcanization. Daga cikin dukkan rubbers, EPDM yana da mafi ƙanƙanta takamaiman nauyi. Bawul ɗin solenoid na iya ɗaukar babban adadin filler da mai ba tare da shafar halayensa ba. Sabili da haka, ana iya samar da mahadi masu ƙarancin farashi. Solenoid bawul tsarin kwayoyin halitta da halaye: EPDM ne terpolymer na ethylene, propylene da wadanda ba conjugated diene. Diolefins suna da tsari na musamman. Ɗaya daga cikin shaidu guda biyu na bawul ɗin solenoid ne kawai za a iya haɗa shi, kuma abubuwan da ba a cika su ba ana amfani da su azaman hanyar haɗin kai. Sauran unsaturated daya ba zai zama babban polymer sarkar, amma zai zama kawai gefe sarkar. Babban sarkar polymer na EPDM cikakke ne. Wannan fasalin bawul ɗin solenoid yana sa EPDM ya jure zafi, haske, oxygen, musamman ozone. EPDM da gaske ba iyakacin duniya ba ne, yana da juriya ga maganin polar da sinadarai, yana da ƙarancin sha ruwa, kuma yana da kyawawan kaddarorin rufewa. Halayen bawul ɗin solenoid: â'  ƙarancin yawa da babban cikawa; â‘¡ juriyar tsufa; â‘¢ juriya na lalata; â‘£ juriyar tururin ruwa; ⑤ tsananin zafin ruwa; â'¥ aikin lantarki; ⑦ elasticity; ⑧ adhesion.
3. VITON Fluorine Roba (FKM)
Rubber mai dauke da fluorine a cikin kwayoyin bawul na solenoid yana da nau'o'in nau'i daban-daban dangane da abun ciki na fluorine, wato, tsarin monomer; roba fluorine na solenoid bawul hexafluoride jerin ya fi silicone roba a high zafin jiki juriya, sinadaran juriya, da solenoid bawul ne resistant zuwa mafi yawan mai Kuma kaushi (sai ketones da esters), yanayin juriya, ozone juriya ne mai kyau, amma sanyi sanyi. juriya ba shi da kyau; Ana amfani da bawul ɗin solenoid gabaɗaya a cikin motoci, babura, B da sauran samfuran, da hatimi a cikin tsire-tsire masu guba. Yanayin zafin aiki shine -20 ° C. ～260℃, ana iya amfani da nau'in juriya mai ƙarancin zafin jiki lokacin da ake amfani da ƙarancin zafin jiki, wanda za'a iya amfani dashi zuwa -40℃, amma farashin ya fi girma.
