Uyilo lwezixhobo zeplastiki eziqinileyo kunye nemibhobho kufuneka iphunyeziwe kwinkqubo yokuphucula, apho izixhobo zokubeka kunye nemixholo ye-realn, i-riber okanye ubungakanani be-angle yomoya, njl. Zichanekile kwaye zichanekile. Hayi, igqiba ukuba ingaba iipropathi zoomatshini kunye nokuchasana kwemveliso yokugqibela kuyahlangabezana nomgangatho ofunekayo, ngoko ke ukulawulwa komgangatho wefilip yefibres yinxalenye ephambili yokuqinisekisa umgangatho wemveliso. Ke yeyiphi imigaqo ekufuneka ilandelwe kulawulo oluphambili lwenkqubo yokwenziwa?
I-1. Inkqubo yokwenziwa kwezixhobo kunye nemibhobho iya kuhlangabezana nezi mfuno zilandelayo:
Izixhobo kunye neenkcazo, inani leendawo, ukulandelelana, ukubumba kunye nenkqubo yokunyanga, i-resin okanye umxholo wefibre, njl. Njl.
② Xa usebenzisa ubumbano lomoya, i-engile yomoya kufuneka ifezekise iimfuno zoyilo;
I-③resin, i-gritiator kunye nekhawulezeni kufuneka zilinganiswe ngokuchanekileyo kwaye zixutywe ngokulinganayo ngaphambi kokusetyenziswa.
2. Uvavanyo lomgangatho wezixhobo kunye nenkqubo yemveliso ye-Pipeline yeNkqubo iya kuhlangabezana nezi mfuno zilandelayo:
Ubungakanani, ubukhulu kunye nomgangatho wokubonakala welitha yangaphakathi kufuneka ihlolwe emva kokuba igqityiwe ukugqitywa;
Umaleko wendlela yenziwe, ubukhulu, ubume bendawo kunye nomgangatho wokubonakala ufanele ukhangelwa.
3. Emva kwezixhobo kunye nemibhobho yenziwa, izinto ezinjengembonakalo, ubungakanani, i-resin reacture, i-resin yomxholo, ukuxhathisa iipropathi zonyango kufuneka kuhlolwe, kwaye kufuneka ifezekise ezi mfuno zilandelayo:
① Umphezulu wangaphakathi kunye nomphezulu wangaphandle kufuneka ugudile kwaye ugudile, kwaye umbala kufuneka ube yinto iyunifomu;
Ubungakanani, iipropathi zoomatshini kunye neepropathi zokulwa nokungena kwi-Ploneration ziya kuhlangabezana neemfuno zoyilo;
③ty umxholo we-resin kunye nokuphambuka okuvumelekileyo kufuneka kuthotyelwe nemigaqo yoyilo. Xa kungekho mgaqo oyilo, umxholo we-resin uvumelekile ukuba ube yi-± 3% yexabiso lexabiso;
④ Emva kokuphiliswa kubushushu begumbi, ubunzima be-barcol akufuneki bube ngaphantsi kwe-80% ye-Barpoli ubunzima bomzimba osetyenziswayo esetyenziswayo. Emva kokufudumeza kunye nokunyanga, i-Barcol Tard ayifanelanga ibe ngaphantsi kwe-85% ye-barpoli yobunzima be-resin esetyenziswayo;
Ubungakanani, ubukhulu kunye nomgangatho wokubonakala welitha yangaphakathi kufuneka ihlolwe emva kokuba igqityiwe ukugqitywa;
Umaleko wendlela yenziwe, ubukhulu, ubume bendawo kunye nomgangatho wokubonakala ufanele ukhangelwa.
3. Emva kwezixhobo kunye nemibhobho yenziwa, izinto ezinjengembonakalo, ubungakanani, i-resin reacture, i-resin yomxholo, ukuxhathisa iipropathi zonyango kufuneka kuhlolwe, kwaye kufuneka ifezekise ezi mfuno zilandelayo:
① Umphezulu wangaphakathi kunye nomphezulu wangaphandle kufuneka ugudile kwaye ugudile, kwaye umbala kufuneka ube yinto iyunifomu;
Ubungakanani, iipropathi zoomatshini kunye neepropathi zokulwa nokungena kwi-Ploneration ziya kuhlangabezana neemfuno zoyilo;
③ty umxholo we-resin kunye nokuphambuka okuvumelekileyo kufuneka kuthotyelwe nemigaqo yoyilo. Xa kungekho mgaqo oyilo, umxholo we-resin uvumelekile ukuba ube yi-± 3% yexabiso lexabiso;
④ Emva kokuphiliswa kubushushu begumbi, ubunzima be-barcol akufuneki bube ngaphantsi kwe-80% ye-Barpoli ubunzima bomzimba osetyenziswayo esetyenziswayo. Emva kokufudumeza kunye nokunyanga, i-Barcol Tard ayifanelanga ibe ngaphantsi kwe-85% ye-barpoli yobunzima be-resin esetyenziswayo;
4. Xa iziphene ezivumelekileyo zidlula kwimigaqo, izixhobo kunye nemibhobho kufuneka ilungiswe, kwaye ukulungiswa kufuneka kuhlangabezane nele migaqo ilandelayo:
Umphezulu we-laminate yelemi kwindawo enesiphene kufuneka ibe ngumhlaba. Emva kokugaya, umphezulu kufuneka ugudise kwaye rhabaxa, kwaye kufuneka ucocwe;
Umphezulu wendawo enesiphene kufuneka upeyintwe nge-resin efanayo ye-resin njengoluhlu oluhlaziyiweyo, kwaye kufuneka lubethelwe ngamatyotyombe aqholiweyo kubungqingqwa bokuyilwa;
③ Umaleko wangaphandle wokulungiswa kwengubo yangaphakathi kufuneka ifakwe kwindawo evalelwe, kwaye i-resin efanayo ye-resin njengoko i-Line yangaphakathi kufuneka isetyenziswe;
④ emva kokulungiswa komaleko wolwakhiwo kugqityiwe, ithuba lokunyanga kunye nonyango lomphezulu kunye nonyango lwangaphakathi okanye umaleko wangaphandle uya kuthobela iimfuno zoyilo;
Emva kokuba kugqityiwe ukulungiswa kwengqimba yangaphandle, xa kukho ukurhabathela kumphezulu, kufuneka iposwe, kwaye i-resin ngaphandle kwePolymerization ye-Air kufuneka ipeyintiwe.
