Funda ngesikhumba esingancibiliki futhi ujabulele impilo enempilo nevumelana nemvelo
Isikhumba esingancibilikiyo siyisikhumba sokwenziwa esivumelana nemvelo. Awekho ama-solvents abilayo aphansi anezelwayo phakathi nenqubo yawo yokukhiqiza, ukufeza i-zero ephumayo kanye nokunciphisa ukungcoliswa kwemvelo.
Umgomo wokukhiqiza walesi sikhumba usekelwe ekuphenduleni okuhambisanayo kwama-resin amabili futhi wenziwa ukomiswa kwezinga lokushisa eliphezulu. Ngesikhathi sokukhiqiza, akukho gesi engcolile noma amanzi angcolile akhiqizwayo, okubonisa umqondo "wokukhiqiza okuluhlaza". Isikhumba esingancibilikisiwe sinezici zokumelana nokuklwebheka, ukumelana ne-hydrolysis, ukumelana nokugqokwa, njll., futhi sedlule inani lamazinga aqinile ezempilo nokuphepha, njengezinkomba ze-European standard REACHER181. Ngaphezu kwalokho, ubuchwepheshe bokukhiqiza besikhumba esingena-solvent buhlanganisa nokusabela kwama-prepolymers kanye nenqubo ye-gelation kanye ne-polyaddition yezingubo, ukuqinisekisa ikhwalithi nokusebenza komkhiqizo.
1. Iyini isikhumba esingancibiliki
Isikhumba esingancibiliki siwuhlobo olusha lwempahla yesikhumba ethuthukiswe eminyakeni yakamuva. Ngokungafani nesikhumba sendabuko, asiqukethe izinyibilikisi eziyingozi zemvelo. Ngokwemibandela ye-layman, iwuhlobo lwesikhumba olwenziwe ngokuhlanganisa izinto zokuphotha ezingancibilikiyo nezinqubo zokwenziwa zendabuko. Ngokuhlanganiswa kobuchwepheshe besimanje kanye nezimiso zokuvikela imvelo kanye nemvelo, iyimpahla yesikhumba enempilo ngempela futhi evumelana nemvelo.
2. Inqubo yokukhiqiza yesikhumba esingancibiliki
Inqubo yokukhiqiza isikhumba esingancibilikiyo ihlukaniswe kakhulu ngezinyathelo ezilandelayo:
1. Ukucubungula impahla eluhlaza. Okokuqala, lungiselela izinto zokusetshenziswa, okuhlanganisa ukukhethwa kwezinto ezibonakalayo, ukuwasha, ukomisa nezinye izinqubo.
2. Ukulungiswa kwezinto zokuphotha. Ubuchwepheshe bokuphotha obungancibiliki busetshenziselwa ukulungisa imicu engancibilikiyo yokukhiqiza isikhumba.
3. Ukuhlanganisa. Izinto zokuphotha zixubene nezinto ezihlukahlukene ezihambisana nemvelo, futhi izinto ezintsha ezinezici zesikhumba zihlanganiswa ngezinqubo ezikhethekile.
4. Ukwakha. Izinto ezihlanganisiwe ziyacutshungulwa futhi zakhiwe, njengokugqamisa, ukusika, ukuthunga, njll.
5. Ngemuva kokucubungula. Ekugcineni, umkhiqizo oqediwe ucutshungulwa ngemuva, njengokudaya, ukunamathela, ukugcotshwa, njll.
III. Izimpawu nezinzuzo zesikhumba esingancibiliki
1. Ukuvikelwa kwemvelo. Isikhumba esingancibilikisiwe asiqukethe izincibilikisi eziphilayo futhi asinalo monakalo endaweni nempilo yabantu.
2. Engasindi. Uma kuqhathaniswa nesikhumba somdabu, isikhumba esingancibiliki silula futhi sigqokeka kalula.
3. Ingagugi. Isikhumba esingancibiliki sinokumelana kangcono nokugqokwa, ukuphefumula, ukuthambile namandla kunesikhumba somdabu.
4. Umbala ogqamile. Umbala wokudaya wesikhumba ongenayo i-solvent uyakhanya futhi uhlala isikhathi eside, akulula ukufiphala, futhi unombala oqinile.
5. Ukwenziwa ngokwezifiso. Inqubo yokukhiqiza isikhumba engancibilikiyo iyavumelana nezimo futhi ingenziwa ngokuvumelana nezidingo zekhasimende ukuze kukhiqizwe imikhiqizo yesikhumba enezici eziqondene nawe.
4. Izinkambu zokufaka isicelo zesikhumba esingena-solvent
Isikhumba esingancibilikisiwe okwamanje sisetshenziswa kakhulu ezicathulweni eziphezulu, izikhwama, imithwalo, imihlobiso yangaphakathi yemoto, ifenisha kanye neminye imikhakha. Namuhla, njengoba ukuvikelwa kwemvelo kuya ngokuya kukhathaza, izinkampani eziningi ezikhiqizayo seziqalile ukucabangela ukuvikelwa kwemvelo ekukhiqizeni nasekusebenzeni, futhi imikhiqizo esebenzisa isikhumba esingenaso i-solvent njengoba izinto zokusetshenziswa ziya ngokuya ziqashelwa ngabathengi.
[Isiphetho]
Isikhumba esingancibiliki siyinto evumelana nemvelo, enempilo, enekhwalithi ephezulu namathemba okusebenza abanzi. Njengoba umthengi ngamunye ebhekana nenkambiso yezidingo zempilo eziluhlaza futhi ezivumelana nemvelo, isikhumba esingancibiliki sesiphenduke into entsha esetshenziswayo esemfashinini, evumelana nemvelo futhi enengqondo.
