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 iinombolo 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.
