Waya inodzima moto, zvinoreva waya ine mamiriro ekudzivirira moto, kazhinji kana iri bvunzo, mushure mekunge waya yapiswa, kana simba rayo rikabviswa, moto uchadzorwa mukati mechikamu chakati, hauzopararire, ine murazvo unodzima moto uye inodzivisa kushanda kweutsi hune chepfu. Waya inodzima moto sechikamu chakakosha chekuchengetedza magetsi, kusarudza zvinhu zvayo kwakakosha, musika wazvino unowanzo shandiswa zvinhu zvewaya zvinodzima moto zvinosanganisiraPVC, XLPE, rabha resilicone uye zvinhu zvinodzivirira mineral.
Kusarudzwa kwewaya inodzivirira moto uye zvinhu zvetambo
Kana chiyero cheokisijeni chezvinhu zvinoshandiswa mutambo inodzivisa moto chakakwira, zvinoita kuti mashandiro emumoto awedzere, asi kana chiyero cheokisijeni chikawedzera, zvinodikanwa kuti munhu arasikirwe nezvimwe zvinhu. Kana hunyanzvi hwemuviri uye maitiro ekugadzira zvinhu zvikadzikira, kushanda kwacho kwakaoma, uye mutengo wezvinhu ukawedzera, saka zvakakosha kusarudza indekisi yeokisijeni zvine musoro uye zvakakodzera, indekisi yeokisijeni yezvinhu zvinodzivirira moto zvinosvika makumi matatu, chigadzirwa chinogona kupasa zvinodiwa zvekirasi C muchiyero, kana zvinhu zvinofukidza jira nekuzadza zviri zvinhu zvinodzivisa moto, chigadzirwa chinogona kusangana nezvinodiwa zvekirasi B nekirasi A. Waya dzinodzivisa moto uye zvinhu zvetambo zvinonyanya kupatsanurwa kuita zvinhu zvinodzivisa moto zvine halogen uye zvinhu zvinodzivisa moto zvisina halogen;
1. Zvinhu zvinodzora moto zvine halogenated
Nekuda kwekuora nekuburitswa kwehydrogen halide kana moto wapisa, hydrogen halide inogona kubata mudzi weHO unoita basa re free radical, zvekuti kupisa kwezvinhu kunononoka kana kudzimwa kuti zvizadzise chinangwa chemurazvo. Zvinowanzoshandiswa ipolyvinyl chloride, neoprene rabha, chlorosulfonated polyethylene, ethylene-propylene rabha nezvimwe zvinhu.
(1) Polyvinyl chloride (PVC) inodzivisa moto: Nekuda kwemutengo wakaderera wePVC, insulation yakanaka uye inodzivisa moto, inoshandiswa zvakanyanya muwaya netambo zvinodzivirira moto. Kuti PVC iwedzere kunonoka kwemoto, halogen flame retardants (decabromodiphenyl ethers), chlorinated paraffins uye synergic flame retardants zvinowanzo wedzerwa mufomura yekuvandudza kunonoka kwemoto kwePVC.
Rabha yeEthylene propylene (EPDM): mahydrocarbon asiri epolar, ane hunhu hwakanaka hwemagetsi, anodzivirira kupisa zvakanyanya, ane kurasikirwa kwakaderera kwe dielectric, asi rabha yeEthylene propylene imhando yezvinhu zvinobvira moto, tinofanira kuderedza mwero werabha yeEthylene propylene inobatanidza, kuderedza kupatsanurwa kwecheni yemamorekuru kunokonzerwa nezvinhu zvine huremu hwakaderera, kuitira kuvandudza hunhu hwemoto hunodzora moto hwezvinhu;
(2) Utsi hushoma uye zvinhu zvinodzora moto zvishoma zve halogen
Zvikurukuru zve polyvinyl chloride ne chlorosulfonated polyethylene zvinhu zviviri. Wedzera CaCO3 neA(IOH)3 mufomura yePVC. Zinc borate neMoO3 zvinogona kuderedza kuburitswa kweHCL uye huwandu hwehutsi hwe polyvinyl chloride inodzivirira moto, nokudaro zvichivandudza kunonoka kwemoto kwechinhu ichi, zvichideredza halogen, acid fog, utsi hunobuda, asi zvinogona kuderedza oxygen index zvishoma.
2. Zvinhu zvinodzora moto zvisina halogen
Mapolyolefin zvinhu zvisina halogen, zvinosanganisira mahydrocarbon anoputsa carbon dioxide nemvura kana apiswa pasina kuburitsa utsi hwakawanda uye magasi anokuvadza. Polyolefin inonyanya kusanganisira polyethylene (PE) uye ethylene – vinyl acetate polymers (E-VA). Zvinhu izvi pachazvo hazvina murazvo unodzivirira, zvinoda kuwedzera murazvo unodzivirira uye phosphorus series flame retardants, kuitira kuti zvigadzirwe kuita zvinhu zvinodzivirira murazvo unodzivirira; Zvisinei, nekuda kwekushaikwa kwemapoka epolar paketani yemamorekuru yezvinhu zvisiri polar zvine hydrophobicity, hukama ne inorganic flame retardants hauna kunaka, zvakaoma kubatana zvakasimba. Kuti polyolefin ivandudze basa repamusoro, surfactants inogona kuwedzerwa mufomura. Kana mu polyolefin yakasanganiswa nemapolymers ane mapoka epolar, kuitira kuti huwandu hwemurazvo unodzivirira huwedzere, kuvandudza hunhu hwemakanika uye hunhu hwekugadzirisa hwezvinhu, ukuwo zvichiwana murazvo unodzivirira hunopfuura. Zvinogona kuonekwa kuti waya netambo zvinodzivirira murazvo zvichiri kubatsira zvikuru, uye kushandiswa kwacho kwakachengeteka zvikuru.
