Ngaphambi kokuvelisa isimo seSongana-Free, kunyanzelekile ukuba ufunde ngononophelo amaxwebhu enkqubo yemveliso kunye neemfuno kunye nezilumkiso zoMyingo wokunamathela esinyibilikayo, ukusetyenziswa, kunye neeparameters. Ngaphambi kokuba kwenziwe imveliso, kuyimfuneko ukuqinisekisa ukuba iimveliso ezenziweyo zisetyenzisiwe zikhululekile. Nje ukuba nayiphi na into engaqhelekanga echaphazela uVeksisity ifunyenwe, kuya kufuneka imiswe kwangoko kwaye inxibelelaniswe nabasebenzi bezobuchwephesha benkampani. Ngaphambi kokuba basebenzise umatshini wokubhabha 'oguqulayo engenasimahla, kunyanzelekile ukuba ibekeke inkqubo yokudibanisa, inkqubo yokuGqibela, kunye neNkqubo yokuLawula kwangaphambili. Phambi kwemveliso yengxowa yeSolvent-imfuneko, kuyimfuneko ukuqinisekisa ukuba umphezulu weendebe zerabha, iiroller eziqinileyo, kunye nezinyeIzinto ezikwizixhobo zomatshini wokucoca ucocekile ucocekile.
Ngaphambi kokuqala, kuyimfuneko ukuqinisekisa kwakhona ukuba umgangatho wemveliso ehlanganisiweyo udibana neemfuno zemveliso yokuveliswa. Uxinzelelo lwefilimu kufuneka lube ngaphezulu kwe-40 dynes, kunye noxinzelelo lomphezulu weefilimu ze-bopa nakwiifilimu ze-Pet kufuneka zibe ngaphezulu kwe-50 dynes. Phambi kwemveliso yobuninzi, ukuthembeka kwefilimu kufuneka kuvavanywe ngovavanyo ukuthintela umngcipheko. Jonga nakuphi na ukonakala okanye ukungabi nangqondo kwimbeko. Ukuba kukho naziphi na izinto ezingaqhelekanga ezifumanekayo, zilahle imbeko kwaye ucoce umatshini wokudibanisa. Emva kokuqinisekisa ukuba akukho zinto zingaqhelekanga kwimbeko, sebenzisa ikomityi yokulahla ukutshekisha ukuba ngaba umlinganiso wokuxuba uchanekile. Imveliso inokuqhubeka kuphela emva kokuphambuka komlinganiselo ngaphakathi kwi-1%.
Ngexesha lenkqubo yokuvelisa, kuyimfuneko ukuqinisekisa umgangatho wemveliso. Emva kokudityaniswa kwesiqhelo kwe-100-150m, umatshini kufuneka umiswe ukuqinisekisa ukuba inkangeleko yenxalenye, isixa esikhathazayo, uxinzelelo, njl.njl. Imveliso ihlangabezana neemfuno. Ngexesha lenkqubo yemveliso, zonke iinkqubo zenkqubo, kubandakanya ubushushu besingqongileyo, umswakama, ubumbeko, kunye neeparamitha zenkqubo ye-parameter, kufuneka zibhalwe phantsi ekwenzeni umkhondo kunye nokuchongwa kwemicimbi esemgangathweni.
Iiparamitha zobugcisa ezinjengokusetyenziswa kunye nokugcinwa kwendawo yokugcina, ixesha lokusebenzisa, ixesha lokusebenza, kunye nomyinge wesimo esimahla kufuneka sibhekise kwincwadana yezobuGcisa bobuGcisa boBugcisa beMveliso. Umswakama kwindibano yocweyo kufuneka ulawulwe phakathi kwe-40% -70%. Xa umswakama yi-70%, unxibelelane nabasebenzi bezobugcisa benkampani kwaye unyuse ngokufanelekileyo icandelo le-Osekote (i-Kangatsha Nets Aunder), kwaye iqinisekise ngovavanyo oluncinci ngaphambi kokusetyenziswa kweBatch. Xa umswakama wendalo esingqongileyo ≤ 30%, unxibelelane nabasebenzi bezobugcisa benkampani kwaye unyuse ngokufanelekileyo i-hydroxyl yecandelo (i-B), kwaye uyiqinisekise ngokusebenzisa ngaphambi kokusetyenziswa kwe-batch. Imveliso kufuneka ikhutshelwe ngononophelo ngexesha lokuhamba kunye nokulayisha kunye nokulayisha, ukunqanda ukucebisa, ukungqubana, kunye nokuthintela umoya kunye nokuvezwa kwelanga kunye nokuvezwa kwelanga. Ifanele igcinwe kwimiqathango epholileyo, enomoya, kunye eyomileyo, kwaye igcinwe itywinwe ixesha lokugcina iinyanga ezi-6. Emva kokuba umsebenzi wobushushu ohlanganisiweyo ugqityiwe, kuluhlu lwamaqondo obushushu amaqondo ocango ngama-35 ° C-50 ° C-° C, kwaye ixesha lokunyanga lihlengahlengiswa ngokwemibala eyahlukileyo. Ukunyanga umswakama kulawulwa ngokubanzi phakathi kwe-40% -70%.
IXESHA LOKUQALA: UJan-25 ukuya ku-2424
