Chigadziriso cheCable Chisingapindi Halogen-Free Flame Retardant

Nekufambira mberi kwetekinoroji, pane kudiwa kuri kuwedzera kwekuchengetedzeka nekuvimbika munzvimbo dzakamanikana uye dzine vanhu vakawanda dzakadai sezviteshi zvepasi pevhu, zvivakwa zvirefu, pamwe nenzvimbo dzeveruzhinji dzakakosha senge ngarava nemidziyo yemagetsi enyukireya. Nekuda kweizvozvo, pane kudiwa kukuru kwekugadzira mhando itsva dzetambo dzine hutsi hushoma, husina halogen, uye hunodzivirira murazvo. Mukutanga kwema1980, nyika dzakabudirira pasi rese dzakatanga kutsvagisa nekugadzira zvinhu netambo dzisingabvisi murazvo hushoma. Tambo dzisingabvisi murazvo husina halogen dzakatanga kushandiswa nekukurumidza uye kushandiswa kwakapararira. MuChina, vagadziri vewaya netambo mumaguta akadai seShanghai, Shenyang, Suzhou, Sichuan, Xiangtan, neWuxi vakagadzira tambo dzemagetsi dzinodzivirira murazvo, tambo dzinochinjika dzinochera rabha, tambo dzechikepe dzinodzivirira murazvo, nezvimwe zvigadzirwa zvine chekuita nazvo.

Zvigadziriso zvinoshandiswa mumidziyo yetambo ine halogen-isina murazvo inodzoreredza murazvo, zvakaita sealuminium hydroxide nemagnesium hydroxide, kuti zvivandudze kubatana uye kubatana pakati pepolyolefin matrix uye inorganic flame retardants. Zvinowedzera kupararira uye kubatana kwealuminium hydroxide nemagnesium hydroxide, nokudaro zvichiwedzera kunonoka kwemurazvo wemidziyo yetambo, zvichideredza utsi, kubuda kweutsi, kusunungurwa kwekupisa, uye kugadzirwa kwecarbon monoxide, zvichiwedzera oxygen index, uye zvichivandudza kuramba kwemvura. Izvi zvinogadzirisa zvakanyanya hunhu hwemakanika nekupisa hwezvinhu. Kuwedzera huwandu hushoma kunogona kuwedzera kushanda kwemakanika, kuwedzera simba rekusunga uye kureba, pamwe nekudzivirira kupisa uye kuramba kwemurazvo.

Mashandisirwo Akajairika:

1. Mushonga wekubatanidza: Unoshandiswa pakushandisa zvinhu zvinoderedza moto zvisina halogen zvakaita sealuminium hydroxide nemagnesium hydroxide kuti zvivandudze kubatana uye kubatana pakati pepolyolefin matrix nezvinodzivirira moto zvisingasanganisike. Kuwedzera 8%–10% kunogona kuwedzera hunhu hwemuchina uye kuramba kupisa kwezvinhu zvakasanganiswa. Kana zvichienzaniswa nezvinhu zvinobatanidza zvakadai sesilane, titanate, aluminate, uye phosphate esters, zvinoita kuti zvinhu zvemuchina zvepolyolefin cable zviwedzere kunaka.
2. Chinosimudzira Kuparadzira: Chinoshandiswa mu polyolefin masterbatches, flame-retardant masterbatches, uye degradable masterbatches. Nekuda kwekubatana kwayo kwakasimba ne pigments, dyes, uye flame retardants, inokurudzira kupararira kwezvinowedzera izvi mu polyolefin carrier resin.
3. Chinosimudzira Kubatanidza: Chine polarity yakakura uye reactivity. Kuwedzera zvishoma kunogona kuvandudza zvakanyanya kupendwa, kunamira, uye kuenderana kwechinhu chacho.
