Global - Premier Dichloromethane: Dareeraha Qiimaha Badan ee Awood siiya Warshadaha Badan
Goobaha Codsiga ee ugu Muhiimsan
Warshadaha rinjiga iyo dahaarka, dichloromethane-keennu waa dareere heer sare ah. Waxay leedahay awood milmi oo aad u fiican, taasoo u oggolaanaysa inay si dhakhso leh oo wax ku ool ah u milmiso noocyada kala duwan ee resins, midabyo, iyo waxyaabo lagu daro oo loo isticmaalo qaacidooyinka rinjiga. Hantidani waxay ka dhigaysaa mid ku habboon codsiyada xoqidda rinjiga. Hadday tahay ka saarista rinjigii hore ee baabuur duug ah, qaab-dhismeed alwaax ah, ama qalab warshadeed, kuwa xoqa rinjiga ee ku salaysan dichloromethane ayaa shaqada si hufan u qaban kara. Intaa waxaa dheer, soo saarista rinjiyada iyo dahaarka cusub, waxay ka caawisaa abuurista isku-darka siman oo isku mid ah, iyadoo hubinaysa tayada midabka iyo dhammaystirka joogtada ah. Soo-saareyaasha rinjiga waxay ku tiirsan yihiin dichloromethane-keena saafiga ah si ay u horumariyaan alaabada ugu sarreysa ee buuxisa baahiyaha kala duwan ee macaamiisha iyo warshadaha.
Warshadaha dawooyinka ayaa sidoo kale si weyn uga faa'iidaysta Dichloromethane-keena Caalamiga ah - Premier. Waxaa loo isticmaalaa hababka soo saarista iyo nadiifinta ee iskudhisyo badan oo dawooyin ah. Awoodda Dichloromethane ee ay si xulasho ah u milmi karto iskudhisyo dabiici ah oo gaar ah ayaa ka dhigaysa qalab qiimo leh oo lagu kala saaro laguna kala saaro walxaha firfircoon ee isku-dhafka adag. Tusaale ahaan, soo saarista daawooyinka laga soo saaro dhirta, waxaa loo isticmaali karaa in lagu soo saaro iskudhisyo firfircoon oo ka yimaada walxaha dhirta. Shirkadaha dawooyinka waxay ku kalsoon yihiin dichloromethane-keena inuu buuxiyo shuruudaha tayada iyo daahirnimada adag ee wax soo saarka daawada, iyagoo hubinaya badbaadada iyo waxtarka alaabadooda.
Warshadaha elektaroonigga, dichloromethane wuxuu door muhiim ah ka ciyaaraa. Waxaa loo isticmaalaa nadiifinta looxyada wareegga daabacan (PCBs) iyo qaybaha kale ee elektaroonigga ah. Inta lagu jiro habka wax soo saarka ee elektaroonigga, PCB-yadu waxay ururin karaan wasakh sida haraaga qulqulka, boodhka, iyo saliidda. Sifooyinka degdega ah ee uumiga iyo kuwa aan gudbin karin ee Dichloromethane waxay ka dhigayaan doorasho aad u fiican oo lagu nadiifiyo qaybahan iyada oo aan waxyeello geysan. Waxay ka caawisaa hagaajinta waxqabadka iyo isku halaynta aaladaha elektaroonigga ah iyadoo laga saarayo wasakhda laga yaabo inay farageliso isku xirka korontada. Soosaarayaasha elektaroonigga ah waxay ku tiirsan yihiin dichloromethane-keena si loo hubiyo wax soo saarka tayada sare leh ee alaabadooda.
Warshadaha xumbada-afuufidda, dichloromethane-keennu waa walax afuufid muhiim ah. Marka loo isticmaalo soo saarista xumbada polyurethane, tusaale ahaan, wuu uumi baxaa inta lagu jiro habka xumbada, isagoo abuuraya xumbo gaas ah oo ballaariya xumbada. Tani waxay keentaa xumbo fudud oo dalool leh oo leh sifooyin dahaadh oo aad u fiican. Xumbo-yadan waxaa si weyn loogu isticmaalaa warshadaha dhismaha si loo dahaadho dhismayaasha, warshadaha alaabta guriga si loo sameeyo barkimooyin raaxo leh, iyo warshadaha baakadaha si loo ilaaliyo walxaha jilicsan. Shirkadaha wax soo saarka xumbo-afuufiddu waxay isticmaalaan dichloromethane-keena si ay u soo saaraan xumbo tayo sare leh oo buuxiya shuruudaha gaarka ah ee codsiyada kala duwan.

Marka la soo koobo
Dichloromethane-keena Caalamiga ah - Premier waxaa lagu duubay weelal tayo sare leh, oo aan daadan karin si looga hortago daadashada ama uumi-baxa inta lagu jiro kaydinta iyo rarista. Dufcad kasta waxay martaa tijaabooyin adag oo lagu xakameynayo tayada, oo ay ku jiraan falanqaynta daahirnimada, go'aaminta qoyaanka, iyo qiimeynta waxqabadka. Hadday tahay soo-saare rinji oo Yurub ah, shirkad dawooyin ah oo Aasiya ku taal, shirkad elektaroonig ah oo Waqooyiga Ameerika ah, ama shirkad wax soo saar xumbo ah oo Afrika ku taal, dichloromethane-keenu waa xalka la isku halleyn karo oo la qabsan karo ee aad u baahan tahay. Waxay bixisaa waxqabad aan la barbar dhigi karin, iyadoo dammaanad qaadaysa inay buuxiso oo ay dhaafto shuruudahaaga gaarka ah ee warshadaha.
