Isigqubuthelo somngxuma wezinto ezidityanisiweyo luhlobo lwesigqubuthelo somngxuma wokuhlola, kwaye iimpawu zaso ziyachazwa: isigqubuthelo somngxuma wokuhlola sidibaniswa yinkqubo ethile esebenzisa ipolymer njengezinto ze-matrix, ukongeza izinto zokuqinisa, izizalisi, njl.
Enyanisweni, isigqubuthelo se-resin manhole (esikwabizwa ngokuba yi-polymer glass fiber reinforced plastic material material material material material material material) luhlobo lwesigqubuthelo se-manhole esisebenzisa i-glass fiber kunye neemveliso zayo (ilaphu leglasi, iteyiphu, i-felt, intambo, njl.njl.) njengezinto zokuqinisa kunye ne-synthetic resin njengezinto ze-matrix. Siqulathe i-polyester resin engagcwaliyo, izizalisi, iziqalisi, izithina, izongezo ezinciphayo, ii-film mold agents, ii-pigment kunye nezinto zokuqinisa, njl.njl., kwaye ke luhlobo olutsha lwemveliso yokugubungela umlambo ebumbeke kubushushu obuphezulu.
Phakathi kwezinto ezongeziweyo, izinto eziqinisiweyo zefayibha (ilaphu leglasi, iteyiphu, i-felt, intambo, njl.njl.) zezona ziphambili, ezibonakaliswa bubunzima obuncinci, amandla amakhulu kunye nemodulus ethile. Umzekelo, izinto ezidityanisiweyo zefayibha yekhabhoni kunye ne-epoxy resin, amandla ayo athile kunye nemodulus ethile zinkulu ngokuphindwe kaninzi kunezo zentsimbi kunye ne-aluminium alloy, kwaye ikwanazo nokuzinza okugqwesileyo kweekhemikhali, ukumelana nokungqubana kunye nokuguguleka, ukuzithambisa, ukumelana nobushushu, ukumelana nokudinwa, ukumelana nokuqhekeka, ukunciphisa ingxolo, ukufakelwa kombane kunye nezinye iimpawu. I-composite yefayibha yegrafiti kunye ne-resin inokufumana izinto ezine-expansion coefficient ephantse ilingane no-zero. Olunye uphawu lwezinto eziqinisiweyo zefayibha yi-anisotropy, ngoko ke ulungiselelo lweefayibha lunokuyilwa ngokweemfuno zamandla kwiindawo ezahlukeneyo zemveliso. Ii-composites ze-aluminium matrix eziqiniswe ngefayibha yekhabhoni kunye nefayibha ye-silicon carbide zisenokugcina amandla aneleyo kunye nemodulus kwi-500 °C.
Izigqubuthelo zemingxuma ezidityanisiweyo zinokwahlulwa zibe yi-BMC kunye ne-SMC ngokweemfuno zemarike, iinkqubo ezahlukeneyo zemveliso kunye nezixhobo:
Izinto zeBMC (DMC) ziikhompawundi zokubumba ngobuninzi. Zidla ngokubizwa ngokuba yi-unsaturated polyester bulk molding compound eTshayina. Izinto ezisetyenziswa kakhulu yi-prepreg efana nentlama exutywe ngokupheleleyo yi-GF (i-glass fiber eqoshiweyo), i-UP (i-unsaturated resin), i-MD (i-filler) kunye nezinye izongezo. Izinto zeDMC zaqala ukusetyenziswa kwiNtshona Jamani yangaphambili nase-United Kingdom ngeminyaka yoo-1960, zaza zaphuhliswa eMelika naseJapan ngeminyaka yoo-1970 kunye noo-1980, ngokulandelelana. Ngenxa yokuba i-BMC bulk molding compound ineempawu zombane ezibalaseleyo, iimpawu zoomatshini, ukumelana nobushushu, ukumelana nokugqwala kweekhemikhali, kwaye iyaziqhelanisa neenkqubo ezahlukeneyo zokubumba, inokuhlangabezana neemfuno zokusebenza kweemveliso ezahlukeneyo, kwaye isetyenziswa kakhulu kwimveliso yeemoto, uthutho lukaloliwe, izixhobo zokwakha, iimveliso zoomatshini nezombane kunye nezinye iindawo.
Ii-SMC composites zii-sheet molding compounds. Izinto eziphambili ezisetyenziswayo zenziwe yi-GF (intambo ekhethekileyo), i-UP (i-resin engagcwaliyo), i-low shrinkage additive, i-MD (i-filler) kunye nezinye izinto ezincedisayo. Yaqala ukubonakala eYurophu ekuqaleni kweminyaka yoo-1960, kwaye malunga nowe-1965, i-United States neJapan zayiphuhlisa ngokulandelelana le mveliso. Ngasekupheleni kweminyaka yoo-1980, ilizwe lam lazisa imigca yemveliso ye-SMC yangaphandle ephucukileyo kunye neenkqubo zemveliso. Izinto ze-SMC ezidityanisiweyo kunye neemveliso zazo ezidityanisiweyo ze-SMC zineempawu zokufakelwa kombane ezibalaseleyo, iimpawu zoomatshini, uzinzo lobushushu, kunye nokumelana nokugqwala kweekhemikhali. Ke ngoko, uluhlu lwezicelo zeemveliso ze-SMC luqhelekile. Indlela yophuhliso yangoku kukutshintsha izinto ze-BMC ngee-SMC composites.
