Ukwakhiwa kwemishini yepulasitiki eqiniswe ngefayibha namapayipi kudinga ukuqaliswa enkambisweni yokukhiqiza, lapho izinto zokwakha kanye nemininingwane, inani lezingqimba, ukulandelana, okuqukethwe yi-resin noma ifayibha, isilinganiso sokuxuba se-resin compound, inqubo yokubumba nokulungisa, usayizi we-angle yokugoqa, njll. kunembile futhi kunembile. Cha, kunquma ukuthi izakhiwo zemishini kanye nokumelana nokugqwala komkhiqizo wokugcina kuyahlangabezana nekhwalithi edingekayo, ngakho-ke ukulawulwa kwekhwalithi yemishini yepulasitiki eqiniswe ngefayibha kanye nenqubo yokukhiqiza amapayipi kuyingxenye ebalulekile yokuqinisekisa ikhwalithi yomkhiqizo. Ngakho-ke yiziphi izimiso okufanele zilandelwe ekulawulweni kwekhwalithi yenqubo yokukhiqiza?
1. Inqubo yokukhiqiza imishini namapayipi kufanele ihlangabezane nezidingo ezilandelayo:
①Izinto zokwakha kanye nemininingwane yezendlalelo, inani lezendlalelo, ukulandelana, inqubo yokubumba kanye nokulungisa, okuqukethwe yi-resin noma i-fiber, njll. kufanele kuhlangabezane nezidingo zomklamo;
② Uma usebenzisa ukubumba okugoqekayo, i-engeli yokugoqa kufanele ihlangabezane nezidingo zomklamo;
③I-resin, i-initiator kanye ne-accelerator kufanele kulinganiswe ngokunembile futhi kuxutshwe ngokulinganayo ngaphambi kokusetshenziswa.
2. Ukuhlolwa kwekhwalithi yenqubo yokukhiqiza imishini kanye namapayipi kufanele kuhlangabezane nezidingo ezilandelayo:
①Usayizi, ukujiya kanye nekhwalithi yokubukeka kwendwangu yangaphakathi kufanele kuhlolwe ngemva kokuqedwa kokukhiqiza;
②Ngemva kokuba ungqimba lwesakhiwo selwenziwe, ukujiya, isakhiwo sesendlalelo kanye nekhwalithi yokubukeka kufanele kuhlolwe.
3. Ngemva kokwenziwa kwemishini namapayipi, izinto ezifana nokubukeka, usayizi, izinga lokupholisa i-resin, okuqukethwe kwe-resin, izakhiwo zemishini kanye nokumelana nokungena kufanele kuhlolwe, futhi kufanele kuhlangatshezwane nezidingo ezilandelayo:
① Ubuso bangaphakathi nobuso bangaphandle kufanele bube bushelelezi futhi bube bushelelezi, futhi umbala kufanele ufane;
②Usayizi, izakhiwo zemishini kanye nezakhiwo zokulwa nokungena kufanele kuhlangabezane nezidingo zomklamo;
③Okuqukethwe kwe-resin kanye nokuphambuka okuvumelekile kufanele kuhambisane nemithethonqubo yokuklama. Uma kungekho mithethonqubo yokuklama, ukuphambuka okuvumelekile kokuqukethwe kwe-resin kufanele kube ngu-±3% wenani lokuklama;
④ Ngemva kokupholisa ekamelweni lokushisa, ubulukhuni beBarcol akufanele bube ngaphansi kuka-80% wobulukhuni beBarcol bomzimba wokubumba i-resin osetshenzisiwe; ngemva kokushisa nokupholisa, ubulukhuni beBarcol akufanele bube ngaphansi kuka-85% wobulukhuni beBarcol bomzimba wokubumba i-resin osetshenzisiwe;
①Usayizi, ukujiya kanye nekhwalithi yokubukeka kwendwangu yangaphakathi kufanele kuhlolwe ngemva kokuqedwa kokukhiqiza;
②Ngemva kokuba ungqimba lwesakhiwo selwenziwe, ukujiya, isakhiwo sesendlalelo kanye nekhwalithi yokubukeka kufanele kuhlolwe.
3. Ngemva kokwenziwa kwemishini namapayipi, izinto ezifana nokubukeka, usayizi, izinga lokupholisa i-resin, okuqukethwe kwe-resin, izakhiwo zemishini kanye nokumelana nokungena kufanele kuhlolwe, futhi kufanele kuhlangatshezwane nezidingo ezilandelayo:
① Ubuso bangaphakathi nobuso bangaphandle kufanele bube bushelelezi futhi bube bushelelezi, futhi umbala kufanele ufane;
②Usayizi, izakhiwo zemishini kanye nezakhiwo zokulwa nokungena kufanele kuhlangabezane nezidingo zomklamo;
③Okuqukethwe kwe-resin kanye nokuphambuka okuvumelekile kufanele kuhambisane nemithethonqubo yokuklama. Uma kungekho mithethonqubo yokuklama, ukuphambuka okuvumelekile kokuqukethwe kwe-resin kufanele kube ngu-±3% wenani lokuklama;
④ Ngemva kokupholisa ekamelweni lokushisa, ubulukhuni beBarcol akufanele bube ngaphansi kuka-80% wobulukhuni beBarcol bomzimba wokubumba i-resin osetshenzisiwe; ngemva kokushisa nokupholisa, ubulukhuni beBarcol akufanele bube ngaphansi kuka-85% wobulukhuni beBarcol bomzimba wokubumba i-resin osetshenzisiwe;
4. Uma amaphutha avumelekile edlula imithetho, imishini namapayipi kufanele kulungiswe, futhi ukulungiswa kufanele kuhlangabezane nemithetho elandelayo:
①Ubuso be-laminate endaweni enesici kufanele bugaywe. Ngemva kokugaya, ubuso kufanele bube bushelelezi futhi bube bukhali, futhi kufanele buhlanzwe;
②Ubuso bendawo enesici kufanele bupendwe ngeglue efanayo nesendlalelo esilungisiwe, futhi kufanele bufakwe uhlaka lwentambo oluqoshiwe ukuze lulingane nobukhulu bomklamo;
③ Ingqimba engaphandle yokulungiswa kwengqimba engaphakathi kufanele ifakwe indwangu ethambile, futhi kufanele kusetshenziswe isembozo se-resin esifanayo nengqimba engaphakathi;
④ Ngemva kokulungiswa kwesendlalelo sesakhiwo, isikhawu sokufakwa kwesendlalelo kanye nokwelashwa kwendawo ngesendlalelo sangaphakathi noma isendlalelo sangaphandle kufanele kuhambisane nezidingo zomklamo;
⑤ Ngemva kokulungiswa kwengqimba yangaphandle, uma kukhona ama-burrs ebusweni, kufanele acwebezelwe, bese kuthi i-resin engenawo umoya ipendwe.
