Isishwankathelo seDip Coating kunye neDip Molding

Inkqubo yeDip Coating kunye neDip Molding

Dip Coating

Inkqubo yokudibanisa imathiriyeli yeplastiki kwintsimbi esele ikhona ngaphambili yaziwa ngokuba dip ukutyabeka. Isinyithi esiza kugqunywa sisebenza njengobumba, sivumela iplastiki okanye i-polymer ukuba ibambelele kuyo ngexesha lenkqubo. Ngaphambi kokuntywila, iinxalenye (kwaye ngamanye amaxesha iziqwenga ezipheleleyo) ezilungiselelwe ukuditshwa ziphathwa kwaye zifudunyezwe ngaphambi kokuba zibekwe ngqo kwipolymer engamanzi (umz. PVC iplastisol ). Ekupholiseni, i-polymer elulwelo ibambelela kwintsimbi kwaye yomelela, okukhokelela kumhlaba ongqindilili weplastiki obonelela ngezinto ezikhuselayo kunye nezihombisayo. Lo mphezulu wongeziweyo ubonelela ukonyuka kokuchasana ngokuchasene nemikrwelo, ukunxiba, ukubola, kunye nezinto zangaphandle ngelixa ukwaphucula ukuqina kunye nokwandisa ubomi benkonzo yamalungu esinyithi. I-Dip coating ayinikezeli nje ngokulula kodwa iqinisekisa ukhuseleko lomsebenzisi ngokubonelela nge-insulating surface kunye nokubamba okuphuculweyo.

Ukusetyenziswa okuqhelekileyo kweengubo zediphu ziquka izixhobo zezandla ezifana neepliers ezixhamla kubuchule bazo bokucinezela okanye ukugoba izinto eziqinileyo ngelixa ugcina ingqibelelo yesixhobo emva kokufaka iplastiki yokwambathisa kwizibambo. Ukongeza, iidiphu zokugquma zifumana into eluncedo kwezinye iimveliso ezinje ngeenqwelo zokuthenga, iibhaskithi, i-tweezers, izivalo, iminqwazi, izithinteli njl.njl., apho ukuqina kufunwa khona.

Ngaphezu koko, iingubo zeplastiki zisebenza njenge-thermal kunye ne-insulators zombane ezisebenzayo ezinikezela ukhuseleko olongezelelweyo xa uphatha izinto ezishushu kwizixhobo zezandla ezifana neepliers kunye nefosholo; zisenokusetyenziselwa iinjongo zokugquma kumalungu e-elektroniki afana neengcingo, iintambo, kunye neeprobe zesixhobo sedijithali.

Dip Ukubumba

Inkqubo yokubumba idiphu iyafana neyokugquma idiphu, kunye nokongezwa kwenyathelo lokudiliza okanye lokukhulula. Ukubumba idiphu kuvumela ukuveliswa kodonga olulodwa, umngxuma, kunye nodonga oluphindwe kabini, ukuphelisa imfuno yeenkqubo ezilandelayo ezifana nokulungisa kunye nokuchithwa. Oku kubangela ukongiwa kwempahla ekrwada ngenxa yokuncipha kwemisebenzi yesibini. Imizekelo yeemveliso zeplastiki ezenziwe ngale nkqubo ibandakanya iiglavu zelatex, ifashoni kunye nempahla yokuhombisa, iikomityi, izivalo zeplastiki, kunye nezixhobo zokuzonwabisa.

Uhlobo lweDip yokugquma kunye nePolymer Molding

Iipolymers eziqhele ukusetyenziswa kwizinto zokugquma ziquka iplastisol, latex, neoprene, polyurethane, kunye ne-epoxy. Uphawu olubalulekileyo lwezi polymers kukukwazi ukufumaneka ngokulula kwifomu yolwelo kwiqondo lokushisa ngaphandle kokufuna ukuqhutyelwa phambili. Ngaphezu koko, phambi kokuqwalasela ukusetyenziswa kwepolymer elulwelo kwidiphu yokwaleka kunye neenkqubo zokubumba idiphu, kufuneka ibe ne-viscosity eyaneleyo ukuthintela ukubaleka okugqithisileyo kumphezulu wokungunda. Ngenxa yoko, i-polymer ihlala phezu komhlaba ide ihlaselwe.

Plastisol

IPlastisol, eyona polymer isetyenziswa ngokuqhelekileyo ekubumbeni idiphu kunye neenkqubo zokugquma, iqulethe i-polyvinyl chloride ehlakazekileyo.PVC) intlaka ngaphakathi kweplastiki engamanzi. Ekufudumezeni, iyomelela kwaye emva koko iphole ibe yinto ethambileyo, enwebekayo eneempawu ezifana nerabha. Eyaziwayo ngokuqina kwayo okungaqhelekanga, ukuxhathisa ukubola, kunye nokuxhathisa impembelelo, iingubo zePlastisol zilungele ukusetyenziswa kombane ngenxa yamandla aphezulu e-dielectric. Ukongeza, imibala inokudityaniswa ukwenza ngokwezifiso ukubonakala kwemveliso yokugqibela.

latex

I-emulsion ye-latex iquka amasuntswana e-polymer amancinci, kunye namasuntswana erabha athatha i-30-40% yetotali. Isebenza njengemathiriyeli ekrwada ebalulekileyo kwimveliso yerabha kwaye inokuba yendalo okanye yokwenziwa. Ipolymer ifikeleleka ngokulula kwaye ayibangeli nkxalabo yetyhefu. Nangona kunjalo, uphononongo oluthile lucebisa ukuba xa luhla lube ngumgubo, abanye abantu banokufumana ukusabela okwaliwayo, okukhokelela ekwehleni kokuthandwa kwayo.

Neoprene

I-Neoprene yenziwe ngepolymerization yerabha ye-neoprene kwaye yenye indawo ye-latex. Iyaziwa ngokumelana neekhemikhali kunye nokuguquguquka.

I-Polyurethanes

Iipolyurethanes zenziwe ngamaqela e-carbamate (okanye i-ethyl carbamate) adityaniswe yi-carbamate. Iyaziwa ngokuguquguquka kwayo kunye nokunwebeka okuphezulu kwi-deformation.

I-Epoxy

I-Epoxy yi-polymer ye-thermosetting ethi, xa amakhonkco e-polymer edibene ngokunqamlezileyo, enze i-coating yamandla aphezulu, iikhemikhali kunye nokumelana nobushushu.
