Ukuthelekiswa kwezinto zeplastiki eziqinisiweyo zeglasi ye-smc kunye nesinyithi kunye nezinye izinto

Ukuthelekiswa kwezinto ezidityanisiweyo ze-SMC kunye nezinto zesinyithi:

1) Ukuqhuba kombane

Zonke iintsimbi ziyakwazi ukudlulisa umbane, kwaye ulwakhiwo lwangaphakathi lwebhokisi olwenziwe ngentsimbi kufuneka lugqunywe nge-insulation, kwaye umgama othile kufuneka ushiywe njengebhanti yokwahlulahlula xa kufakwa ibhokisi. Kukho ingozi ethile efihlakeleyo yokuvuza kunye nokuchithwa kwendawo.

I-SMC yiplastiki ye-thermosetting enokumelana nomphezulu okungaphezulu kwe-1012Ω. Yinto yokukhusela. Inokumelana nobushushu obuphezulu kunye nombane wokuqhekeka, onokuthintela iingozi zokuvuza, ugcine iipropati ezilungileyo ze-dielectric kumaza aphezulu, kwaye ayibonakali okanye ayivali. Ukusasazwa kwee-microwave kunokuthintela ukutshayiswa kombane kwebhokisi, kwaye ukhuseleko luphezulu.

2) Inkangeleko

Ngenxa yokucubungula isinyithi okuntsonkothileyo, umphezulu wembonakalo ulula. Ukuba ufuna ukwenza iimilo ezintle, iindleko ziya kunyuka kakhulu.

I-SMC kulula ukuyila. Yenziwe ngumngundo wesinyithi phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu, ngoko ke imo inokuba yodwa. Umphezulu webhokisi uyilwe ngeeprotrusions ezimile okwedayimani, kwaye i-SMC ingafakwa umbala ngokungacwangciswanga. Imibala eyahlukeneyo ingenziwa ngokwezifiso ngokweemfuno zabathengi.

3) Ubunzima

Ubunzima obuthile besinyithi ngokubanzi yi-6-8g/cm3 kwaye ubunzima obuthile bezinto ze-SMC ngokubanzi abudluli kwi-2 g/cm3. Ubunzima obuphantsi bulungele ukuthuthwa, nto leyo eyenza ukufakwa kube lula kwaye kube lula, kwaye konga kakhulu iindleko zokuhamba kunye nokufakela.

4) Ukumelana nokugqwala

Ibhokisi yesinyithi ayimelani nokugqwala kwe-asidi kunye ne-alkali, kwaye kulula ukuyigqwala kwaye yonakalise: ukuba inyangwa ngepeyinti yokulwa nomhlwa, okokuqala, iya kuba nempembelelo ethile kwindalo esingqongileyo ngexesha lenkqubo yokupeyinta, kwaye ipeyinti entsha yokulwa nomhlwa kufuneka ithathwe rhoqo emva kweminyaka emi-2. Isiphumo sokumelana nomhlwa sinokufezekiswa kuphela ngonyango, oluyandisa kakhulu iindleko zokulungiswa emva kokulungiswa, kwaye kunzima ukuyisebenzisa.

Iimveliso ze-SMC zinokumelana okuhle nokugqwala kwaye zinokumelana ngempumelelo nokugqwala kwamanzi, ipetroli, utywala, ityuwa ye-electrolytic, i-acetic acid, i-hydrochloric acid, iikhompawundi ze-sodium-potassium, umchamo, i-asphalt, i-asidi eyahlukeneyo nomhlaba, kunye nemvula ene-asidi. Imveliso ngokwayo ayinayo ukusebenza okuhle kokulwa nokwaluphala. Umphezulu wemveliso unomaleko okhuselayo onokumelana okukhulu kwe-UV. Ukhuseleko oluphindwe kabini lwenza imveliso ibe nokusebenza okuphezulu kokulwa nokwaluphala: ifanelekile kuzo zonke iintlobo zemozulu embi, kwindawo engqongileyo ye--50C—+150 degrees Celsius, Isenokugcina iipropati ezilungileyo zomzimba nezoomatshini, kwaye inqanaba lokhuseleko yi-IP54. Imveliso inobomi obude benkonzo kwaye ayinakugcinwa.

I-SMC xa ithelekiswa nezinye ii-thermoplastics:

1) Ukumelana nokwaluphala

Iithermoplastics azinawo amandla okuguga. Xa zisetyenziswa ngaphandle ixesha elide, itawuli iya kuvezwa ekukhanyeni nasemvuleni, kwaye umphezulu uya kutshintsha umbala ngokulula kwaye ube mnyama, uqhekeke kwaye ube buthathaka, nto leyo echaphazela amandla kunye nenkangeleko yemveliso.

I-SMC yiplastiki ye-thermosetting, enganyibilikiyo kwaye enganyibilikiyo emva kokuba inyibilikile, kwaye inokumelana nokugqwala okuhle. Ingagcina amandla aphezulu kunye nenkangeleko entle emva kokusetyenziswa ixesha elide ngaphandle.

2) Ukuqhekeka

Zonke ii-thermoplastics zineempawu zokurhubuluza. Phantsi kwesenzo samandla angaphandle exesha elide okanye amandla okuzihlola, kuya kubakho ukuguquguquka okuthile, kwaye imveliso egqityiweyo ayinakusetyenziswa ixesha elide. Emva kweminyaka emi-3-5, kufuneka itshintshwe iyonke, nto leyo ebangela inkunkuma eninzi.

I-SMC yinto yokulungisa ubushushu, engenawo umkhenkce, kwaye inokugcina imeko yayo yokuqala ngaphandle kokuguquka emva kokusetyenziswa ixesha elide. Iimveliso ze-SMC ngokubanzi zingasetyenziswa ubuncinane iminyaka elishumi.

3) Ukuqina

Izinto ze-thermoplastic ziqinile kakhulu kodwa azinabugocigoci obaneleyo, kwaye zilungele kuphela iimveliso ezincinci, ezingathwali mithwalo, kungekhona iimveliso ezinde, ezinkulu nezibanzi.
