Utshintsho lobushushu ngexesha lenkqubo yokubumba i-FRP luyinkimbinkimbi ngakumbi. Ngenxa yokuba iplastiki ayisebenzisi kakuhle ubushushu, umahluko wobushushu phakathi kombindi nomphetho wezinto mkhulu ekuqaleni kokubumba, nto leyo eya kubangela ukuba impendulo yokubumba kunye nokudibanisa ingaqalanga ngaxeshanye kwiileya zangaphakathi nezangaphandle zezinto.
Ngenxa yokuba kungonakalisa amandla kunye nezinye izalathisi zokusebenza kwemveliso, ukunyusa ngokufanelekileyo ubushushu bokubumba kuyanceda ukunciphisa umjikelo wokubumba nokuphucula umgangatho wemveliso.
Ukuba ubushushu bokubumba buphantsi kakhulu, kungekuphela nje ukuba izinto ezinyibilikisiweyo zine-viscosity ephezulu kunye nokungaguquguquki kakuhle, kodwa kwanokuba i-crosslinking reaction kunzima ukuqhubeka ngokupheleleyo, amandla emveliso akaphezulu, inkangeleko ayicacanga, kwaye ukunamathela kwe-mold kunye nokuguqulwa kokukhupha kwenzeka ngexesha lokudilizwa.
Ubushushu bokubumba bubushushu bokubumba obuchazwe ngexesha lokubumba. Le parameter yenkqubo imisela iimeko zokudluliselwa kobushushu bokubumba kwizinto ezikumqolo, kwaye inempembelelo enkulu ekunyibilikeni, ukuhamba kunye nokuqina kwezinto.
Izinto zomaleko womphezulu zinyangwa kwangethuba ngobushushu ukuze zenze umaleko weqokobhe eliqinileyo, ngelixa ukuncitshiswa kamva kwezinto zomaleko wangaphakathi kuthintelwa ngumaleko weqokobhe eliqinileyo wangaphandle, nto leyo ebangela uxinzelelo oluhlala lucinezelekile kumaleko womphezulu wemveliso ebunjiweyo, kwaye umaleko wangaphakathi kukho uxinzelelo oluhlala luxinezelekile, ukubakho koxinzelelo oluhlala lushiyekile kuya kubangela ukuba imveliso igobe, iqhekeke kwaye inciphise amandla.
Ke ngoko, ukuthatha amanyathelo okunciphisa umahluko wobushushu phakathi kwangaphakathi nangaphandle kwezinto ezikwindawo yokubumba kunye nokuphelisa ukungalingani kokulungiswa yenye yeemeko ezibalulekileyo zokufumana iimveliso ezikumgangatho ophezulu.
Ubushushu bokubumba be-SMC buxhomekeke kubushushu obuphezulu be-exothermic kunye nesantya sokuphilisa senkqubo yokuphilisa. Ngokwesiqhelo uluhlu lobushushu olunobushushu obuphezulu bokupholisa oluphantsi kancinci luluhlu lobushushu bokupholisa, oluqhele ukuba malunga ne-135 ~ 170℃ kwaye lumiselwa kuvavanyo; izinga lokuphilisa likhawuleza Ubushushu benkqubo buphantsi, kwaye ubushushu benkqubo obuphezulu.
Xa usenza iimveliso ezixineneyo, thatha umda ophezulu woluhlu lobushushu, kwaye ukwenza iimveliso ezixineneyo kungathatha umda ophantsi woluhlu lobushushu. Nangona kunjalo, xa usenza iimveliso ezixineneyo ezinobunzulu obukhulu, umda ophantsi woluhlu lobushushu kufuneka uthathwe ngenxa yenkqubo ende yokuthintela ukuqina kwezinto ngexesha lenkqubo yokuhamba kwamanzi.
