Umuyoboro wa Nylon, Umuyoboro wa Rubber, Umuyoboro w'icyuma

Kugeza ubu, imiyoboro ikoreshwa mu modoka irashobora kugabanywamo ibyiciro bitatu: umuyoboro wa nylon, umuyoboro wa reberi n'umuyoboro w'icyuma.Imiyoboro ikoreshwa cyane ya nylon ni PA6, PA11 na PA12.Ibi bikoresho uko ari bitatu byitwa aliphatic Pa. PA6 na PA12 ni impeta ifungura polymerisation naho PA11 ni polymerisiyonike.

1. Ibyiza byanylon umuyoboroni ibi bikurikira: resistance kurwanya amavuta meza (lisansi, mazutu), amavuta yo gusiga amavuta, hamwe no kurwanya imiti.Resistance Kurwanya ubushyuhe buke: PA11 irashobora kwihanganira ingaruka zubushyuhe buke bwa - 50 ℃ na PA12 birashobora kwihanganira ingaruka zubushyuhe buke bwa - 40 ℃.▼ Ubushyuhe bwagutse bushyushye: igipimo cy'ubushyuhe bwa PA11 ni - 40 ~ 125 ℃, naho umwanya wa PA12 ni - 40 ~ 105 ℃.Nyuma yo gupima gusaza kuri 125 ℃, 1000h, 150 ℃ na 16h, umuyoboro wa PA11 ufite imikorere myiza yubushyuhe buke.Kurwanya ogisijeni na zinc umunyu wangirika: kurwanya 50% zinc chloride yumuti urenga 200H.Kurwanya aside ya batiri na ozone.Material ni ibikoresho byo kwisiga hamwe no kurwanya kunyeganyega, kwihanganira kwambara, kurwanya umunaniro hamwe na coefficient de friction.Resistance Kurwanya UV no gusaza kwikirere: UV irwanya ibara risanzwe PA11 irashobora gukoreshwa mumyaka 2.3-7.6 bitewe n'uturere dutandukanye;Ubushobozi bwo kurwanya ultraviolet yumukara PA11 bwiyongereyeho inshuro enye nyuma yo kongeramo anti-ultraviolet.

Uburyo bwo gutunganya umuyoboro wa nylon ni: procedure uburyo bwo gukuramo ② gushiraho uburyo procedure uburyo bwo guterana procedure uburyo bwo gutahura.Muri rusange,nylon umuyoboroifite ibyiza byinshi mumikorere ugereranije numuyoboro wicyuma, mugihe nibyiza mukurwanya imiti yangirika no kwambara ugereranijeumuyoboro w'icyuma, igira uruhare runini mukugabanya uburemere bwimodoka nigiciro cyumusaruro.

2. Hariho byinshirubber hoseimiterere yimodoka, nuburyo bwibanze burimo ubwoko busanzwe, ubwoko bwongerewe imbaraga nubwoko busize.

Imiterere shingiro ya rubber hose muri iki gihe, ibikoresho bikoreshwa cyane mu isoko ni FKM, NBR, Cr, CSM na eco: temperature ubushyuhe bwa serivisi bwa FKM (fluororubber) ni 20 ~ 250 ℃, bukoreshwa cyane kuri O- impeta, kashe ya peteroli, urwego rwimbere rwalisansinibindi bicuruzwa.Temperature ubushyuhe bwa serivisi ya NBR (reberi ya nitrile) ni 30 ~ 100 ℃, ikoreshwa cyane cyane muri reberi, kashe mpeta na kashe ya peteroli.Temperature ubushyuhe bwa serivisi ya Cr (chloroprene rubber) ni 45 ~ 100 ℃, bukoreshwa cyane cyane kuri kaseti, hose, gutwikira insinga, reberi ya plaque gasketi 'ivumbi, nibindi temperature temperature ubushyuhe bwa serivisi bwa CSM (chlorosulfonated polyethylene rubber) ni 20 ~ 120 ℃, ikoreshwa cyane cyane mumapine, kaseti, icyuma cyometseho icyuma, insinga, ibice byamashanyarazi, O-impeta, inzugi zifunga umuryango nidirishya, nibindi temperature ubushyuhe bwa serivisi bwibidukikije (reberi ya Chloroether) ni 40 ~ 140 ℃, ikoreshwa cyane cyane kumpeta ishyushye, diaphragm, shitingi, reberi, nibindi.

3. Nkubwoko bwumuyoboro ukomeye,umuyoboro w'icyumaifite ibyiza byuburemere buremereye, igiciro kinini kandi kuvunika byoroshye.Kubwibyo, ibigo byinshi kandi byinshi byimodoka bihitamo kureka gukoresha imiyoboro yicyuma.Kugeza ubu, umuyoboro wa aluminiyumu urakenewe cyane muri sisitemu yo guhumeka.Nyamara, imbaraga zingana, umuvuduko ukabije hamwe no gusaza kwimiyoboro yicyuma nibyiza kuruta iby'imiyoboro ya nylon hamwe na rubber.
