Emhlabeni wonkhe - I-Dichloromethane Lehamba Embili: Sincibilikisi Lesingakabaluleki Lesinika Timboni Letinyenti Emandla
Tindzawo Letinkhulu Tesicelo
Embonini yekupenda kanye nekugcobisa, i-dichloromethane yetfu iyinhlanganisela lenkhulu. Inemandla lamahle kakhulu ekuncibilikisa, lokuyivumela kutsi incibilikise ngekushesha futsi ngemphumelelo tinhlobo letehlukene tema resin, ema pigments, kanye netintfo letingetiwe letisetjentiswa ekwakhiweni kwepende. Le mpahla yenta kutsi ilungele kusetjentiswa kwekukhumula upende. Noma ngabe kususa pende lomdzala emotweni lendzala, sakhiwo setigodvo, noma imishini yetimboni, i-dichloromethane - lesekelwe ekukhipheni pende ingakhona kwenta lomsebenti kahle. Ngetulu kwaloko, ekukhiciteni emapendi lamasha kanye nekugcobisa, kusita ekwakheni ingcucuko lebushelelezi nalefanako, kucinisekisa umbala lofanako kanye nelizinga lekucedza. Bakhiciti bependi batsembele ku dichloromethane yetfu lesetulu - lehlantekile kwenta imikhicito lesetulu - lesetulu lehlangabetana netidzingo letehlukahlukene tebatsengisi kanye netimboni ngekufana.
Imboni yemitsi iphindze futsi inzuze kakhulu ku-Dichloromethane yetfu yeMhlaba wonkhe - Ndvunankhulu. Isetjentiswa ekukhipheni kanye nasetinchubeni tekuhlanta emakhompawundi lamaningi emitsi. Likhono le Dichloromethane lekukhetsa kuncibilikisa emakhompawundi lakhetsekile etilwane kwenta kutsi kube lithulusi lelibalulekile ekuhlukaniseni kanye nekuhlukanisa tintfo letisebentako kusuka etinhlanganisweni letiyinkimbinkimbi. Sibonelo, ekukhiciteni imitsi lesuselwa etitjalweni, ingasetjentiswa kukhipha emakhompawundi lasebenta ngetilwane kusuka etintfweni tetitjalo. Tinkampani temitsi tetsemba i-dichloromethane yetfu kutsi ihlangabetane netidzingo leticinile telizinga kanye nebumsulwa bekukhicita imitsi, kucinisekisa kuphepha nekusebenta kahle kwemikhicito yato.
Embonini ye-elekthronikhi, i-dichloromethane idlala indzima lebalulekile. Isetjentiselwa kuhlanta emabhodi lashicilelwe (ema-PCB) kanye naletinye tintfo te-elekthronikhi. Ngesikhatsi senchubo yekukhicita i-elekthronikhi, ema-PCB angabutsela ndzawonye tintfo letingcolisako letifana netinsalela te-flux, lutfuli, kanye ne oyili. Timphahla te Dichloromethane letisheshako - letihhwamukako naletingacondzisi tenta kutsi kube kukhetsa lokuhle kakhulu kwekuhlanta letintfo ngaphandle kwekubangela kulimala. Kuyasita kwenta ncono kusebenta kanye nekwetsembeka kwetintfo te-elekthronikhi ngekususa tintfo letingcolisako letingaphazamisa kuxhumana kwagezi. Bakhiciti be-elekthronikhi batsembele ku-dichloromethane yetfu kucinisekisa kukhicita lokusezingeni leliphakeme - kwemikhicito yabo.
Emkhakheni wekuphefumula wegwebu, i-dichloromethane yetfu iyintfo lebalulekile yekuphefumula. Uma isetjentiswa ekukhiciteni emagwebu e-polyurethane, sibonelo, iyahwamuka ngesikhatsi sekukhipha emagwebu, kwenta emabhubhu egesi lakhulisa legwebu. Loku kuphumela kumafomu lalula, lanetikhala lanetintfo letinhle kakhulu tekuvikela. Lamagwebu asetjentiswa kakhulu embonini yekwakha yekuvikela takhiwo, embonini yefenisha yekwenta imicamelo lekhululekile, kanye nasembonini yekupakisha yekuvikela tintfo letibucayi. Tinkampani tekukhicita emagwebu tisebentisa i-dichloromethane yetfu kukhicita emagwebu lasesigabeni lesiphakeme lahlangabetana netidzingo letitsite tekusebentisa letehlukene.

Ngalokufishane
I-Dichloromethane yetfu yemhlaba wonkhe - lephakeme ipakishwe etitjani letisezingeni lelisetulu, letingavuti - kuvikela noma ngukuphi kuvuta noma kuhhwamuka ngesikhatsi sekugcina kanye nekutfutsa. Sicumbi ngasinye sidlula ekuhlolweni lokucinile kwekulawula lizinga, kufaka ekhatsi kuhlatiya bucwebe, kuncuma lokucuketfwe ngumswakama, kanye nekuhlolwa kwekusebenta. Noma ngabe ungumkhiciti wepende eYurophu, inkampani yemitsi e-Asia, inkampani ye-elekthronikhi eNyakatfo Melika, noma ibhizinisi lekhicita igwebu - e-Afrika, i-dichloromethane yetfu sisombululo lesetsembekile nalesivumelanako losidzingako. Iniketa kusebenta lokungenakulinganiswa, kucinisekisa kutsi ihlangabetana futsi idlula tidzingo takho letitsite temboni.
