Xa ukhetha i-fiberglass ekumgangatho ophezulu onqunyulwe i-strand mat yokwenza izikhephe zokuloba ze-fiberglass, kubalulekile ukuqonda iingenelo kunye nokufaneleka kwayo. Nasi isishwankathelo sendlela yokukhetha, kodwa kubalulekile ukuqaphela ukuba ukuhambelana ne-resin, ngakumbi malunga nokukhulelwa, yinto ebalulekileyo. Ke ngoko, eyona ndlela ilungileyo kukuqhuba iimvavanyo zokungena kwiziko lokuvelisa izikhephe ze-fiberglass ukuqinisekisa ukufaneleka.

Ngaphaya koko, i-fiberglass egayiweyo ye-strand mat isetyenziswa ikakhulu kwiinkqubo zokubumba izandla, kwaye iimveliso ezidibana nezi meko zilandelayo zithathwa ngokuba zikumgangatho ophezulu:

1.Ubunzima obufanayo kwindawo nganye yeyunithi. Lo mba ubalulekile njengoko uchaphazela zombini ubukhulu kunye namandla. Ngaphantsi kokukhanya, kulula ukuchonga iimveliso ezinokungalingani okuphawulekayo, okunokubonwa ngeso lenyama. Ngelixa ukufana kobunzima kwiyunithi nganye akuqinisekisi ubukhulu obuhambelanayo-ekubeni oku kukwaxhomekeke ekufaniseni umsantsa phakathi kweerola ezibandayo-ukwahluka kwe-mat ubukhulu kunokukhokelela kumxholo we-resin ongalinganiyo kwimveliso yokugqibela ye-fiberglass. Imethi enobunzima obufanayo ithande ukufunxa intlaka ngokulinganayo. Uvavanyo oluqhelekileyo lokufana lubandakanya ukusika i-mat ibe ngamaqhekeza angama-300mm x 300mm ububanzi bayo, ubala amanani ngokulandelelanayo, umlinganiselo weqhekeza ngalinye, kwaye ubale ukutenxa kobunzima.

2.Nokusasaza imisonto ngaphandle kokuqokelelana okugqithisileyo kuyo nayiphi na indawo. I-dispersibility yeentambo ezinqunqiweyo ngexesha lemveliso yinto ebalulekileyo echaphazela ukufana kobunzima be-mat kwindawo yeyunithi kunye nokusabalalisa imicu kwi-mat. Emva kokunqunyulwa, i-strand bundle nganye kufuneka ihlakazeke kakuhle. Ukuba ezinye iinyanda azisasazeki kakuhle, zinokwenza imigca engqindilili kwimethi.

3. Umphezulu kufuneka ukhululeke ekuweni okujikelezayo okanye ukudodobala. Amandla okuqina omatshini we-mat abonisa umgangatho wokudibanisa phakathi kwee-strand bundles.

4.Akukho kungcola kufuneka kubekho kwimethi.

5.Imethi kufuneka yomiswe kakuhle. I-mat efunxa ukufuma iya kuqhekeka xa isasaziwe kwaye icholwa kwakhona. Isiqulatho sokufuma esingaphantsi kwe-0.2% samkelekile ngokubanzi kwiinkqubo eziqhelekileyo zokuvelisa.

6.Ukufakwa ngokupheleleyo kwe-resin kubalulekile. Ukunyibilika kwe-styrene kunokusetyenziswa njenge-proxy yokuvavanya ukunyibilika kwe-mat kwi-polyester resin, njengoko uvavanyo oluthe ngqo lokunyibilika kwi-polyester lunokutya ixesha kwaye kunzima ukulilinganisa. Ukusebenzisa i-styrene njengenye indlela yamkelwe kwihlabathi jikelele kwaye isemgangathweni.

7.Emva kokufakwa kwe-resin, iintambo akufanele ziyeke.

8.I mat kufuneka kube lula degas.

Ezi nqobo zokugweba zinceda ekuqinisekiseni ukukhethwa kwemethi ye-fiberglass ekumgangatho ophezulu, ibalulekile ekwenzeni izikhephe zokuloba ezihlala ixesha elide nezisebenzayo.
