Uyilo lwezixhobo zeplastiki eziqinisiweyo kunye nemibhobho kufuneka luphunyezwe kwinkqubo yokuvelisa, apho izinto ezicwangcisiweyo kunye neenkcukacha, inani leeleya, ulandelelwano, umxholo we-resin okanye ifayibha, umlinganiselo wokuxuba we-resin compound, inkqubo yokubumba kunye nokunyanga, ubungakanani be-angle yokujika, njl.njl. zichanekile kwaye zichanekile. Hayi, imisela ukuba iimpawu zoomatshini kunye nokumelana nokugqwala kwemveliso yokugqibela ziyahlangabezana nomgangatho ofunekayo, ngoko ke ulawulo lomgangatho wezixhobo zeplastiki eziqinisiweyo kunye nenkqubo yokuvelisa imibhobho yinxalenye ebalulekileyo yokuqinisekisa umgangatho wemveliso. Ngoko ke yeyiphi imigaqo ekufuneka ilandelwe kulawulo lomgangatho wenkqubo yokuvelisa?
1. Inkqubo yokuvelisa izixhobo kunye nemibhobho iya kuhlangabezana neemfuno ezilandelayo:
①Izixhobo kunye neenkcukacha zeeleya, inani leeleya, ulandelelwano, inkqubo yokubumba kunye nokunyanga, umxholo we-resin okanye wefayibha, njl. kufuneka zihlangabezane neemfuno zoyilo;
② Xa usebenzisa i-winding molding, i-winding angle kufuneka ihlangabezane neemfuno zoyilo;
③I-resin, i-initiator kunye ne-accelerator kufuneka zilinganiswe ngokuchanekileyo kwaye zidityaniswe ngokulinganayo phambi kokusetyenziswa.
2. Ukuhlolwa komgangatho wezixhobo kunye nenkqubo yokuvelisa imibhobho kuya kuhlangabezana neemfuno ezilandelayo:
①Ubungakanani, ubukhulu kunye nomgangatho wembonakalo yelayini yangaphakathi kufuneka kujongwe emva kokuba imveliso igqityiwe;
②Emva kokuba umaleko wesakhiwo wenziwe, ubukhulu, ulwakhiwo lomaleko kunye nomgangatho wembonakalo kufuneka kujongwe.
3. Emva kokuba izixhobo kunye nemibhobho zenziwe, izinto ezifana nenkangeleko, ubungakanani, inqanaba lokunyanga i-resin, umxholo we-resin, iimpawu zoomatshini kunye nokumelana nokungena kufuneka zihlolwe, kwaye kufuneka zihlangabezane neemfuno ezilandelayo:
① Umphezulu wangaphakathi nomphezulu wangaphandle kufuneka ube mpuluswa kwaye uthambile, kwaye umbala ufane;
②Ubukhulu, iimpawu zoomatshini kunye neempawu zokulwa nokungena kufuneka zihlangabezane neemfuno zoyilo;
③Umxholo we-resin kunye nokuphambuka okuvumelekileyo kufuneka kuhambelane nemigaqo yoyilo. Xa kungekho mgaqo woyilo, ukuphambuka okuvumelekileyo komxholo we-resin kufuneka kube yi-±3% yexabiso loyilo;
④ Emva kokunyibilika kubushushu begumbi, ubunzima beBarcol akufuneki bube ngaphantsi kwe-80% yobunzima beBarcol bomzimba osetyenziswayo wokubumba i-resin; emva kokufudumeza nokubumba, ubunzima beBarcol akufuneki bube ngaphantsi kwe-85% yobunzima beBarcol bomzimba osetyenziswayo wokubumba i-resin;
①Ubungakanani, ubukhulu kunye nomgangatho wembonakalo yelayini yangaphakathi kufuneka kujongwe emva kokuba imveliso igqityiwe;
②Emva kokuba umaleko wesakhiwo wenziwe, ubukhulu, ulwakhiwo lomaleko kunye nomgangatho wembonakalo kufuneka kujongwe.
3. Emva kokuba izixhobo kunye nemibhobho zenziwe, izinto ezifana nenkangeleko, ubungakanani, inqanaba lokunyanga i-resin, umxholo we-resin, iimpawu zoomatshini kunye nokumelana nokungena kufuneka zihlolwe, kwaye kufuneka zihlangabezane neemfuno ezilandelayo:
① Umphezulu wangaphakathi nomphezulu wangaphandle kufuneka ube mpuluswa kwaye uthambile, kwaye umbala ufane;
②Ubukhulu, iimpawu zoomatshini kunye neempawu zokulwa nokungena kufuneka zihlangabezane neemfuno zoyilo;
③Umxholo we-resin kunye nokuphambuka okuvumelekileyo kufuneka kuhambelane nemigaqo yoyilo. Xa kungekho mgaqo woyilo, ukuphambuka okuvumelekileyo komxholo we-resin kufuneka kube yi-±3% yexabiso loyilo;
④ Emva kokunyibilika kubushushu begumbi, ubunzima beBarcol akufuneki bube ngaphantsi kwe-80% yobunzima beBarcol bomzimba osetyenziswayo wokubumba i-resin; emva kokufudumeza nokubumba, ubunzima beBarcol akufuneki bube ngaphantsi kwe-85% yobunzima beBarcol bomzimba osetyenziswayo wokubumba i-resin;
4. Xa iziphene ezivumelekileyo zigqitha imigaqo, izixhobo kunye nemibhobho kufuneka zilungiswe, kwaye ukulungiswa kufuneka kuhlangabezane nale migaqo ilandelayo:
①Umphezulu we-laminate kwindawo enesiphene kufuneka ucolwe. Emva kokusila, umphezulu kufuneka ube mtyibilizi kwaye urhabaxa, kwaye kufuneka ucocwe;
②Umphezulu wokubekwa kwendawo enesiphako kufuneka upeyintwe ngeglue yeresin efanayo nomaleko olungisiweyo, kwaye kufuneka ugqunywe nge-strand mat enqunqiweyo ukuze ibe nobukhulu boyilo;
③ Umaleko ongaphandle wokulungiswa kwe-inside lining kufuneka ugqunywe nge-surface felt, kwaye kusetyenziswe i-resin cover efanayo ne-inside lining;
④ Emva kokuba ukulungiswa komaleko wolwakhiwo kugqityiwe, ixesha lokuvala kunye nonyango lomphezulu kusetyenziswa umaleko wangaphakathi okanye umaleko womphezulu wangaphandle kufuneka kuhambelane neemfuno zoyilo;
⑤ Emva kokuba kugqityiwe ukulungiswa komaleko wangaphandle, xa kukho iibherrs kumphezulu, kufuneka zipolishwe, kwaye i-resin engena-air polymerization kufuneka ipeyintwe.
