Uhlolojikelele lwe-Dip Coating kanye ne-Dip Molding

Inqubo ye-Dip Coating kanye ne-Dip Molding

I-Dip Coating

Inqubo yokuhlanganisa impahla yepulasitiki ocezu lwensimbi olwake lwaba khona ngaphambili lwaziwa ngokuthi cwilisa enamathela. Insimbi okufanele iboshwe isebenza njengesikhunta, okuvumela ipulasitiki noma i-polymer ukuthi ibambelele kuyo ngesikhathi senqubo. Ngaphambi kokucwiliswa, izingxenye (futhi ngezinye izikhathi izingcezu eziphelele) ezihloselwe ukucwiliswa ziyaphathwa futhi zishiswe ngaphambi kokuba zifakwe ngokuqondile ku-polymer ewuketshezi (isb. PVC i-plastisol ). Lapho ipholisa, i-polymer ewuketshezi inamathela ensimbi futhi iyaqina, okuholela endaweni ewugqinsi yokwemboza yepulasitiki enikeza kokubili izakhiwo zokuvikela nezokuhlobisa. Le ndawo ethuthukisiwe inikeza ukumelana okukhulayo ngokumelene nokuklwebheka, ukuguga, ukugqwala, nezici zangaphandle kuyilapho ithuthukisa ukuqina nokwelula impilo yesevisi yezingxenye zensimbi. I-Dip coating ayinikezi nje kuphela ukunethezeka kodwa futhi iqinisekisa ukuphepha komsebenzisi ngokunikeza indawo evikelayo enokubambelela okuthuthukisiwe.

Izicelo ezivamile zama-dip coatings zihlanganisa amathuluzi esandla afana namapliers azuza ekhonweni lazo lokuminyanisa noma ukugoba izinto eziqinile kuyilapho elondoloza ubuqotho bamathuluzi ngemva kokufaka ipulasitiki enamathela ezibambeni. Ukwengeza, ama-dip coatings athola usizo kweminye imikhiqizo ehlukahlukene njengezinqola zokuthenga, obhasikidi, ama-tweezers, izivalo, izigqoko, izivalo njll., lapho kufunwa ukuqina.

Ngaphezu kwalokho, izimbobo zepulasitiki zisebenza njengezivikeli ezishisayo ezishisayo nezikagesi ezinikeza ukuvikeleka okwengeziwe lapho uphatha izinto ezishisayo ngamathuluzi esandla afana namapulangwe namafosholo; zingaphinda zisetshenziselwe izinjongo zokwahlukanisa ezingxenyeni ze-elekthronikhi njengezintambo, amakhebuli, nama-probe amathuluzi edijithali.

I-Dip Molding

Inqubo yokubunjwa kwe-dip ifana neye-dip coating, ngokungezwa kwesinyathelo sokudiliza noma sokuthulula. Ukubunjwa kwe-dip kuvumela ukukhiqizwa kodonga olulodwa, izingxenye ezingenalutho, nezikabili, okuqeda isidingo sezinqubo ezilandelayo ezifana nokusikwa nokususa. Lokhu kubangela ukongiwa kwempahla ngenxa yokuncipha kwemisebenzi yesibili. Izibonelo zemikhiqizo yepulasitiki ekhiqizwa ngale nqubo ihlanganisa amagilavu ​​e-latex, imfashini nezimpahla zokugqoka, izinkomishi, izivalo zepulasitiki, nezingxenye zemishini yokuzijabulisa.

Uhlobo lwe-Dip coating kanye ne-Molding Polymer

Ama-polymers asetshenziswa kakhulu ukwenza izinto zokumboza afaka i-plastisol, i-latex, i-neoprene, i-polyurethane, ne-epoxy. Isici esibalulekile salawa ma-polymer amandla awo okutholakala kalula efomini eliwuketshezi ekamelweni lokushisa ngaphandle kokudinga ukucubungula okwengeziwe. Ngaphezu kwalokho, ngaphambi kokucabangela ukusetshenziswa kwe-polymer ewuketshezi ekuhlanganiseni kwe-dip kanye nezinqubo zokubumba, kufanele ibe ne-viscosity eyanele ukuvimbela ukugeleza ngokweqile okuvela ebusweni besikhunta. Ngenxa yalokho, i-polymer ihlala phezulu kuze kube yilapho iphulukiswa.

I-Plastisol

I-Plastisol, i-polymer evame ukusetshenziswa kakhulu ekubumbeni idiphu nasezinqubweni zokuhlanganisa idiphu, iqukethe i-polyvinyl chloride ehlakazeke kahle (PVC) i-resin ngaphakathi kwe-plasticizer ewuketshezi. Lapho ishisa, iyaqina futhi iphole ibe into ethambile, enwebekayo enezakhiwo ezifana nerabha. Idume ngokuqina kwayo okungavamile, ukumelana nokugqwala, kanye nokumelana nomthelela, izimbotshana ze-Plastisol zifaneleka ngokukhethekile ukusetshenziswa kukagesi ngenxa yamandla azo aphezulu e-dielectric. Ukwengeza, ama-colorants angahlanganiswa ukuze enze ngendlela oyifisayo ukubukeka komkhiqizo wokugcina.

Latex

I-emulsion ye-latex iqukethe izinhlayiya ze-polymer ezincane, ezinezinhlayiya zenjoloba ezibalelwa ku-30-40% wengqikithi. Isebenza njengempahla eluhlaza ebalulekile ekukhiqizeni irabha futhi ingaba yemvelo noma yokwenziwa. I-polymer ifinyeleleka kalula futhi ayibangeli ukukhathazeka ngobuthi. Kodwa-ke, ucwaningo oluthile lusikisela ukuthi uma lehla libe yimpushana, abanye abantu bangase babe nokungezwani komzimba, okuholela ekwehleni kokuthandwa kwayo.

Neoprene

I-Neoprene yenziwe nge-polymerization yerabha ye-neoprene futhi ingenye ye-latex. Iyaziwa ngokumelana kwayo namakhemikhali nokuvumelana nezimo.

Ama-Polyurethanes

Ama-polyurethanes akhiwe amaqembu e-carbamate (noma i-ethyl carbamate) axhunywe yi-carbamate. Iyaziwa ngokuguquguquka kwayo kanye nokunwebeka okuphezulu kokuguquguquka.

I-Epoxy

I-Epoxy iyi-polymer ye-thermosetting okuthi, uma amaketanga e-polymer exhunywe ngokuphambana, yakhe ukunamathela kwamandla aphezulu, amakhemikhali nokumelana nokushisa.
