Isticmaalka Alaabta
Sida walxo kiimiko ah oo muhiim ah oo ceeriin ah iyo dareere leh waxqabad aad u fiican, dimethylformamide (DMF) ayaa inta badan loo isticmaalaa polyurethane, acrylic, daawo, sunta cayayaanka, midabada, elektiroonigga iyo warshadaha kale. Waxaa inta badan loo isticmaalaa soo saarista maqaar qoyan oo qoyan sida wax lagu dhaqo oo lagu daweeyo warshadaha poliurethane. Warshadaha dawooyinka sida dhexdhexaadinta daroogada synthetic, oo si ballaaran loo isticmaalo soosaarka doxycycline, cortisone, sulfonamide; Sida dareeraha warshadaha fiber akril, waxaa inta badan loo isticmaalaa qalalan qalalan ee fiber akril. Warshadaha sunta cayayaanka ee loogu talagalay isku-dhafka waxtarka sare leh iyo sunta sunta cayayaanka ee hooseeya; Warshadaha dheeha sida dareeraha dheeha; In warshadaha elektarooniga ah sida daasadda daasado qaybo ka mid ah deminta iyo nadiifinta guddiga wareegga; Warshadaha kale waxaa ka mid ah sidayaasha gaasaska khatarta ah, dareerayaasha loogu talagalay crystallization daroogada, xabagta, iwm.
Xidhmada iyo Kaydinta
Xiritaanka: Baakadaha waa la habeyn karaa ereyga dhoofintu wuxuu noqon karaa bad, hawo, muunad ama tiro yar waxaa lagu rari karaa DHL, FEDEX, EMS iyo TNT.
Kaydinta: Ku kaydi deegaan qabow oo qalalan, oo ka fog iftiinka qorraxda tooska ah
Shuruudaha kaydinta badbaadada leh, oo ay ku jiraan wax kasta oo aan ku habboonayn
Laga soocay walxaha aan isqaban karin. Fiiri Khatarta Kiimikada. Weelka si adag u xidh meel engegan oo hawo fiican leh. Weelasha la furay waa in si taxadar leh dib loogu xiraa oo lagu hayaa toosan si looga hortago in ay daadsanto. Qabo oo ku kaydi gaaska aan shaqaynayn.
