M'pofunika kugwiritsa ntchito lawi retardant chingwe nthawi zina zofunika kwambiri zofunika pa lawi retardant ntchito chingwe, monga kufala mphamvu ndi kugawa mizere, subways, tunnels, malo magetsi, petrochemicals, nyumba mkulu-nyamuka, etc. Kawirikawiri, Chingwe choletsa moto chimafunika kudzazidwa kapena kukulunga ndi zinthu zoletsa moto mkati. Chingwe choletsa moto komanso chosagwira kutentha kwambiri ndi chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri podzazitsa zoletsa moto chifukwa champhamvu yake yoletsa moto.
Magalasi a fiberglass ndi asbestos ndi ma carcinogens oopsa omwe ndi owopsa kwa ogwira ntchito komanso chilengedwe pakagwiritsidwe ntchito. Kuphatikiza apo, magalasi a fiberglass ndi asibesitosi ali ndi mphamvu yokoka komanso kuchuluka kwa madzi, makamaka akagwiritsidwa ntchito mu chingwe chamagetsi choletsa moto, zomwe zimatsogolera ku tepi yamkuwa.
Chingwe chotchingira moto komanso chopanda kutentha kwambiri chimakhala ndi mawonekedwe ofewa, makulidwe a yunifolomu, osakhala ahygroscopic komanso index yayikulu ya okosijeni. Ndi chinthu chabwino kwambiri chosinthira chingwe cha fiberglass ndi zingwe za asbestos pakadali pano. Lilibe magalasi a fiberglass, asibesitosi, halogen ndi zinthu zina zovulaza, palibe kuipitsidwa kwa chilengedwe, sikuvulaza thupi la munthu. Ndipo kulemera kwa yuniti kwa chingwe chotchingira moto komanso chingwe chotchinga kutentha kwambiri ndi 1/5 mpaka 1/3 ya chingwe cha fiberglass ndi chingwe cha asbestos.
Chingwe chotchingira moto komanso chopanda kutentha kwambiri chomwe chimagwiritsidwa ntchito ngati zinthu zosakhala ndi hygroscopic zotchingira moto popangira ma cabling filler mu chingwe chamagetsi choletsa moto, chingwe cha migodi chosagwira moto, chingwe chapamadzi choletsa malawi, chingwe cha rabara cha silikoni chosapsa ndi moto, chingwe chosagwira moto, moto(oxygen) -chingwe chotsekereza chosanjikiza ndi zingwe zina zomwe zimafuna kuti zisamawotche ndi kutentha kwambiri. Makamaka, ntchitoyo ndi bwino mu kalasi A lawi retardant sing'anga-voltage mphamvu chingwe kudzaza amene si zimachitika makutidwe ndi okosijeni pamene kukhudzana ndi tepi mkuwa.
Chingwe chotchingira moto komanso chopanda kutentha kwambiri chomwe tidapereka chili ndi izi:
1) Maonekedwe ofewa, kupindika kwaulere, palibe delamination ndi kuchotsa ufa popinda kuwala.
2) yunifolomu kupindika ndi khola awiri akunja.
3) Palibe fumbi likuwuluka panthawi yogwiritsira ntchito.
4) Mlozera wapamwamba wa okosijeni womwe ungafikire kalasi ya Class A retardant grade.
5) Kuthamanga kwabwino komanso kosasunthika.
Amagwiritsidwa ntchito makamaka kudzaza kusiyana kwa chingwe chapakati cha chingwe chamagetsi choletsa moto, chingwe chotchingira moto, chingwe cham'madzi choletsa moto, chingwe cha rabara ya silikoni yoletsa moto, chingwe chosagwira moto, chingwe chosanjikiza moto (oksijeni) ndi zina. zingwe zomwe zimafuna kuti zisamawotche ndi kutentha kwambiri.

Chingwe chotchingira moto komanso kutentha kwambiri chimakhala ndi njira ziwiri zokhazikitsira malinga ndi momwe zimakhalira.
1) Kukula kwakung'ono (88cm * 55cm * 25cm): Chogulitsacho chimakulungidwa muthumba lakanema loletsa chinyezi ndikuyika muthumba loluka.
2) Kukula Kwakukulu (46cm * 46cm * 53cm): Chogulitsacho chimakulungidwa mu thumba la filimu losatetezedwa ndi chinyezi ndikulongedza m'thumba la polyester lopanda madzi.
1) Zogulitsazo ziyenera kusungidwa m'nyumba yosungiramo zinthu zoyera, zowuma komanso zokhala ndi mpweya wabwino.
2) Zogulitsazo zisamangidwe pamodzi ndi zinthu zoyaka moto ndipo zisakhale pafupi ndi magwero a moto.
3) Chogulitsacho chiyenera kupewa kuwala kwa dzuwa ndi mvula.
4) Chogulitsacho chiyenera kudzazidwa kwathunthu kuti chiteteze chinyezi ndi kuipitsa.
5) Chogulitsacho chiyenera kutetezedwa kupsinjika kwakukulu ndi kuwonongeka kwa makina panthawi yosungira.
