Uma ukhetha i-fiberglass eqoshwe ngentambo yekhwalithi ephezulu yokwenza izikebhe zokudoba ze-fiberglass, kubalulekile ukuqonda izinzuzo nokufaneleka kwayo. Nasi isifinyezo senqubo yokukhetha, kodwa kubalulekile ukuqaphela ukuthi ukuhambisana nenhlaka, ikakhulukazi mayelana nokukhulelwa, kuyisici esibalulekile. Ngakho-ke, indlela engcono kakhulu ukwenza izivivinyo zokungena endaweni yokukhiqiza izikebhe ze-fiberglass ukuze kuqinisekiswe ukufaneleka.

Ngaphezu kwalokho, i-fiberglass chopped strand mat isetshenziswa ngokuyinhloko ezinqubweni zokubumba zokubeka izandla, futhi imikhiqizo ehlangabezana nalezi zimo ezilandelayo ngokuvamile ibhekwa njengekhwalithi ephezulu:

1.Isisindo esifanayo endaweni yeyunithi ngayinye. Lesi sici sibalulekile njengoba sithinta kokubili ukushuba namandla. Ngaphansi kokukhanya, kulula ukuhlonza imikhiqizo enokungalingani okuphawulekayo, okungabonakala ngeso lenyama. Nakuba ukufana kwesisindo endaweni yeyunithi ngayinye akuqinisekisi ukushuba okungaguquki—njengoba lokhu kuphinde kuncike ekufaneni kwegebe phakathi kwamarola abandayo—ukwehluka kogqinsi lwe-mat kungaholela ekuqukethwe kwe-resin okungalingani emkhiqizweni wokugcina we-fiberglass. I-mat enesisindo esifanayo ijwayele ukumunca inhlaka ngokulinganayo. Ukuhlolwa okujwayelekile kokufana kuhilela ukusika umata ube yizicucu ezingu-300mm x 300mm ububanzi bawo, uzifake izinombolo ngokulandelana kwazo, ukale ucezu ngalunye, nokubala ukuchezuka kwesisindo.

2.Ngisho nokusatshalaliswa kwezintambo ngaphandle kokunqwabelana ngokweqile kunoma iyiphi indawo. Ukuhlakazeka kwezintambo eziqotshiwe ngesikhathi sokukhiqiza kuyisici esibalulekile esithinta ukufana kwesisindo se-mat endaweni ngayinye kanye nokusatshalaliswa kwezintambo kumata. Ngemuva kokusika, inqwaba ye-strand ngayinye kufanele ihlakazeke kahle. Uma ezinye izinyanda zingahlakazi kahle, zingakha imigqa ewugqinsi kumata.

3.Indawo engaphezulu kufanele ingabi ne-roving fallout noma i-delamination. Amandla okuqina wemishini we-mat abonisa ikhwalithi yokubopha phakathi kwezibopho ze-strand.

4.Akukho ukungcola okufanele kube khona kumata.

5.Umata kumele womiswe kahle. Umata omunce umswakama uzowa lapho wendlalwa futhi uthathwa futhi. Umswakama ongaphansi kuka-0.2% wamukelekile ezinqubweni zokukhiqiza ezijwayelekile.

6.Ukufakwa okuphelele kwe-resin kubalulekile. Ukunyibilika kwe-styrene kungasetshenziswa njengommeleli wokuhlola ukunyibilika kwe-mat ku-polyester resin, njengoba ukuhlolwa okuqondile kokuncibilika ku-polyester kungase kudle isikhathi futhi kube nzima ukukubala. Ukusebenzisa i-styrene njengenye indlela kuye kwamukelwe emhlabeni wonke futhi kwamiswa.

7.Ngemva kokufakwa kwe-resin, izintambo akufanele zixege.

8.I-mat kufanele ibe lula ukuyikhipha.

Lezi zindlela zisiza ukuqinisekisa ukukhethwa kwe-fiberglass mat yekhwalithi ephezulu, ebalulekile ekukhiqizeni izikebhe zokudoba ezihlala isikhathi eside nezisebenzayo.
