(2) Danko na guduro cakuda ya kamata ya dace da aikin gyare-gyare.Ana iya yin gyare-gyare da yawa ga danko na gaurayawar guduro ta hanyar diluting tare da styrene, amma ƙara da yawa filaye da diluting da styrene zai haifar da raguwar aikin FRP.Dankin gaurayawan guduro wani lokaci yana da matukar tasiri ta hanyar adadin hadawa, yanayin hadawa, ko kari na masu gyara saman filler.
(3) Halayen warkarwa na cakuda guduro yakamata su dace da yanayin gyare-gyare.Siffofin warkarwa na gaurayawan guduro wani lokaci ana yin tasiri ta hanyar filler ɗin kanta ko abin da aka shayar da shi ko gauraye danshi da abubuwan waje a cikin filler.
(4) Cakudawar guduro yakamata ta kasance karɓaɓɓe na ɗan lokaci.Ga sabon abu na daidaitawa da rabuwa na filler saboda tsayawa har yanzu, ana iya hana shi wani lokaci ta hanyar ba da guduro tare da thixotropy.Wasu lokuta, ana amfani da hanyar gujewa a tsaye da ci gaba da motsawa na inji don hana sasantawar filler, amma a cikin wannan yanayin, yakamata a yi la'akari da hana sasantawa da tarawar filler a cikin bututun daga kwandon da ke dauke da mahautsini zuwa kafawar. site.Lokacin da wasu filaye na microbead suna da saurin rarrabuwa zuwa sama, ya zama dole a sake tabbatar da darajar.
(5) Ƙarfafawar cakudawar resin ya kamata ya dace da matakin fasaha na mai aiki.Bugu da kari na fillers gabaɗaya rage bayyana gaskiya na guduro cakuda da kuma rage ductility na guduro a lokacin layering.Saboda haka, impregnation, defoaming aiki, da hukunci a lokacin gyare-gyaren ya zama da wahala.Ya kamata a yi la'akari da waɗannan abubuwan don ƙayyade rabo na cakuda guduro.
(6) Ya kamata a mai da hankali ga takamaiman nauyi na cakuda guduro.Lokacin amfani da filler azaman kayan haɓaka don rage farashin kayan, takamaiman nauyin cakuda guduro yana ƙaruwa idan aka kwatanta da guduro, wani lokacin ba sa saduwa da ƙimar da ake tsammani na rage farashin kayan cikin hankali.
(7) Ya kamata a bincika tasirin gyaran fuska na filler.Masu gyaran gyare-gyare na filler suna da tasiri wajen rage danko na gaurayawan guduro, kuma masu gyara shimfidar wuri daban-daban na iya inganta ƙarfin injin wani lokaci baya ga juriyar ruwa, juriyar yanayi, da juriya na sinadarai.Haka kuma akwai nau’o’in filaye da aka yi musu magani a sama, wasu kuma suna amfani da abin da ake kira “Hanyar hadawa gaba daya” wajen gyara saman filaye.Wato, lokacin da ake hada gaurayawan guduro, ana haɗa masu filaye da masu gyarawa tare da guduro, wani lokacin tasirin yana da kyau sosai.
(8) Ya kamata a aiwatar da zubar da kumfa a cikin cakudawar guduro sosai.Ana amfani da filler sau da yawa a cikin nau'i na ƙananan foda da barbashi, tare da wani yanki na musamman na musamman.A lokaci guda, akwai kuma sassa da yawa inda ƙananan foda da barbashi ke haɗuwa da juna.Domin tarwatsa waɗannan filaye a cikin guduro, resin yana buƙatar yin motsawa mai tsanani, kuma ana jawo iska a cikin cakuda.Bugu da ƙari, ana kuma jawo iska a cikin babban ƙarar filaye.Sakamakon haka, iskar da ba za a iya misaltuwa ba ta gauraya cikin gaurayen resin da aka shirya, kuma a wannan jiha, FRP da ake samu ta hanyar samar da ita don yin gyare-gyaren tana da saurin haifar da kumfa da kuraje, wani lokacin kuma ta kasa cimma aikin da ake sa ran.Lokacin da ba zai yiwu a yi cikakken zubar da kumfa ba kawai ta tsaye bayan haɗuwa, ana iya amfani da tacewa jakar siliki ko rage matsi don cire kumfa.
Baya ga abubuwan da ke sama, ya kamata kuma a ɗauki matakan rigakafin ƙura a cikin yanayin aiki yayin amfani da filaye.Abubuwa irin su ultrafine particulate silica wanda ya hada da silica kyauta, alumina, diatomaceous earth, daskararre duwatsu, da dai sauransu ana rarraba su a matsayin Class I ƙura, yayin da calcium carbonate, gilashin foda, gilashin gilashi, mica, da dai sauransu an rarraba su azaman Class II ƙura.Har ila yau, akwai ka'idoji game da kulawar kulawar nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'i nau'in).Dole ne a shigar da na'urorin shaye-shaye na gida kuma dole ne a yi amfani da kayan aikin kariyar aiki sosai lokacin da ake sarrafa irin waɗannan na'urori masu foda.
