Ukutshintsha kweqondo lokushisa ngexesha lenkqubo yokubumba i-FRP inzima kakhulu.Ngenxa yokuba iplastiki ingumbhexeshi ombi wobushushu, umahluko weqondo lobushushu phakathi kweziko kunye nomda wezinto eziphathekayo mkhulu ekuqaleni kokubumba, okuya kubangela ukuba ukunyangwa kunye nokudibanisa ukudibanisa kungaqali ngexesha elifanayo ngaphakathi kunye nangaphakathi. iileya zangaphandle zezinto.
Kwisiseko sokungonakalisi amandla kunye nezinye izibonakaliso zokusebenza zemveliso, ngokufanelekileyo ukwandisa ubushushu bokubumba kunenzuzo ukunciphisa umjikelo wokubumba kunye nokuphucula umgangatho wemveliso.
Ukuba iqondo lokushisa lokubumba liphantsi kakhulu, kungekhona nje kuphela izinto ezinyibilikisiweyo ezine-viscosity ephezulu kunye nokungahambi kakuhle kwamanzi, kodwa nangenxa yokuba ukuphendula kwe-crosslinking kunzima ukuqhubeka ngokupheleleyo, amandla emveliso ayikho phezulu, imbonakalo ibuthuntu, kunye nokunamathela kwesikhunta kunye ne-ejection deformation. kwenzeka ngexesha lokukhulelwa.
Ubushushu bokubumba bubushushu bokubumba obuchazwe ngexesha lokubumba.Le nkqubo ipharamitha imisela iimeko zokutshintshwa kobushushu besikhunta kwizinto eziphathekayo kwi-cavity, kwaye inefuthe eliqinisekileyo ekunyibilikeni, ukuhamba kunye nokuqina kwezinto.
Izinto zomaleko womphezulu zinyangwa kwangaphambili bubushushu ukuze zenze umaleko weqokobhe olukhuni, ngelixa ukucutheka konyango lwamva lwesixhobo somaleko sangaphakathi kuthintelwe ngumaleko weqokobhe olukhuni ongaphandle, okukhokelela kuxinzelelo olushiyekileyo olucinezelayo kumaleko omphezulu wemveliso ebunjiweyo, kwaye Umaleko ongaphakathi kukho Kukho uxinzelelo olushiyekileyo, ubukho boxinzelelo olushiyekileyo buya kubangela ukuba imveliso ijike, iqhekeze kwaye inciphise amandla.
Ngoko ke, ukuthatha amanyathelo okunciphisa ukuhluka kweqondo lokushisa phakathi kwangaphakathi nangaphandle kwezinto eziphathekayo kwi-mold cavity kunye nokuphelisa ukunyanga okungalinganiyo enye yeemeko ezibalulekileyo zokufumana iimveliso eziphezulu.
Iqondo lobushushu lokubumba i-SMC lixhomekeke kwiqondo lobushushu lencopho ye-exothermic kunye nenqanaba lokunyanga lenkqubo yokunyanga.Ngokwesiqhelo uluhlu lweqondo lobushushu olunobushushu obusezantsi kancinane bokunyanga iqondo lobushushu obunyangayo, obumalunga ne-135～170℃ kwaye bugqitywe ngolingo;izinga lokunyanga likhawuleza Ubushushu benkqubo buphantsi, kwaye ubushushu benkqubo enezinga elicothayo lokunyanga liphezulu.
Xa usenza iimveliso ezinodonga olubhityileyo, thatha umda ophezulu woluhlu lobushushu, kwaye ukwenza iimveliso ezinodonga olungqingqwa kunokuthatha umda osezantsi woluhlu lobushushu.Nangona kunjalo, xa usenza iimveliso ezinobumba obuncinci kunye nobunzulu obukhulu, umda ophantsi woluhlu lweqondo lokushisa kufuneka uphinde uthathwe ngenxa yenkqubo ende yokuthintela ukuqina kwezinto ngexesha lokuhamba.
