C). Isango. Imbaleki kufuneka ibe banzi kwaye ibe mfutshane ngokusemandleni, kwaye indawo yesango kufuneka isethwe ngokungqinelana nokuncipha kunye nenkqubo yokuncipha, kwaye kufuneka kusetyenziswe ifriji yefriji xa kufanelekile.
D). Umphezulu wediski kufuneka ubushelelezi kunye noburhabaxa obuphantsi (kukhethwa ukuba ibe ngaphantsi kwe-0.8);
E). Imingxuma yokukhupha. Itanki kufuneka lanele ukukhupha umoya kunye negesi kunyibilike ngexesha.
F). Ngaphandle kwe-PET, ubukhulu bodonga akufuneki bunciphe kakhulu, ngokubanzi bungabi ngaphantsi kwe-l mm.
4. Iingxaki ezifuna ingqwalaselo kwinkqubo yokubumba ngenaliti (kubandakanya iimfuno zoomatshini bokubumba inaliti) Ukwenzela ukunciphisa uxinzelelo lwangaphakathi kunye neziphene kumgangatho wobuso, ingqalelo kufuneka ihlawulwe kule miba ilandelayo kwinkqubo yokubumba yenaliti.
A). Isikulufa esikhethekileyo kunye nenaliti yokubumba umatshini onomlomo ohlukileyo wokulawula ubushushu kufuneka kukhethwe.
B). Inaliti ephezulu yokufuma kufuneka isetyenziswe kubushushu benaliti ngaphandle kokubola kwentlaka yeplastiki.
C). Inaliti uxinzelelo: ngokubanzi ngaphezulu ukoyisa isiphako se-melt viscosity ephezulu, kodwa uxinzelelo oluphezulu kakhulu luya kuvelisa uxinzelelo lwangaphakathi, oluya kuthi lukhokelele ekutshatyalalisweni nzima kunye nokusilela;
D). Isantya senaliti: Kwimeko yokwanelisa ukuzaliswa, kufanelekile ngokubanzi ukuba sezantsi, kwaye kungcono ukusebenzisa inaliti ekhawulezayo yokucotha inqanaba elininzi;
E). Uxinzelelo lokubamba ixesha kunye nokwenza ixesha: kwimeko yokwanelisa ukugcwaliswa kwemveliso ngaphandle kokuvelisa ukudakumba kunye namaqamza, kufanele ukuba ibe mfutshane kangangoko ukunciphisa ixesha lokunyibilika emgqonyeni;
F). Isantya sokujija kunye noxinzelelo lwangasemva: kwisiseko sokwanelisa umgangatho weplastikhi, kufanele ukuba ibe sezantsi kangangoko ukuthintela ukubakho kokuhla;
G). Ubushushu beMold: Umgangatho wokupholisa weemveliso unefuthe elikhulu kumgangatho, ke ubushushu besikhunta kufuneka sikwazi ukuyilawula ngokuchanekileyo inkqubo yayo, ukuba kunokwenzeka, ubushushu besikhunta kufuneka bube ngaphezulu.
5. Eminye imiba
Ukuthintela ukonakala komphezulu womgangatho, iarhente yokukhupha kufuneka isetyenziswe kancinci kangangoko ekubunjweni ngenaliti ngokubanzi, kwaye izinto ezinokuphinda zisetyenziselwe akufuneki zibe ngaphezulu kwe-20%.
Kuzo zonke iimveliso ngaphandle kwePET, kufuneka kwenziwe emva kokuphelisa uxinzelelo lwangaphakathi, i-PMMA kufuneka yomiswe kwi-70-80 ° C kumjikelo womoya oshushu kangangeeyure ezi-4, iPC kufuneka itshiswe nge-110-135 ° C kumoya ococekileyo, i-glycerin Iparafini engamanzi, njl. Ixesha lixhomekeke kwimveliso, kwaye eyona mfuno iphezulu ingaphezulu kweeyure ezili-10. I-PET kufuneka iye kolulwa nge-biaxial ukufumana iipropathi ezilungileyo zoomatshini.

IV --- Itekhnoloji yokubumba Inaliti yeplastikhi engabonakaliyo
Iimpawu zetekhnoloji yeplastikhi esekuhleni: Ngaphandle kwezi ngxaki zixeliweyo zingasentla, iiplastikhi eziselubala nazo zinempawu ezithile zobuchwephesha, ezishwankathelwe ngolu hlobo lulandelayo:
1. Inkqubo yenkqubo ye-PMMA. I-PMMA ine-viscosity ephezulu kunye nefluidity engalunganga, ke kufuneka itofwe ngobushushu obuphezulu kunye noxinzelelo lwenaliti. Impembelelo yeqondo lobushushu lenaliti ingaphezulu koxinzelelo lwenaliti, kodwa ukonyuka koxinzelelo lwenaliti kuluncedo ekuphuculeni izinga lokuncipha kweemveliso. Uluhlu lobushushu ngenaliti lubanzi, iqondo lobushushu elinyibilikayo yi-160 ° C kwaye ubushushu bokubola yi-270 ° C ngoko ke uluhlu lobushushu bezinto zibanzi kwaye inkqubo ilungile. Ke ngoko, ukuphucula ubumanzi, singaqala ngobushushu benaliti. Ifuthe elibi, ukunganyangeki ukunxiba okungalunganga, kulula ukukrwela, kulula ukwaphuka, ke kufuneka siphucule ubushushu besifa, siphucule inkqubo yokunciphisa, ukoyisa ezi ziphene.
2. Inkqubo yenkqubo yePC PC ine-viscosity ephezulu, ukunyibilika okuphezulu kunye nokungabi namanzi, ke kufuneka itofwe kubushushu obuphezulu (phakathi kwe-270 kunye ne-320T). Ngokuthelekisa, uluhlu lolungelelwaniso lobushushu bezinto luyinto encinci, kwaye ukusebenza akunakulunga njenge-PMMA. Uxinzelelo lwe-Inaliti alunampembelelo kuncinci, kodwa ngenxa ye-viscosity ephezulu, isafuna uxinzelelo olukhulu lwenaliti. Ukuthintela uxinzelelo lwangaphakathi, ixesha lokubamba kufuneka libe lifutshane kangangoko kunokwenzeka. Izinga lokuncipha likhulu kwaye ubungakanani buzinzile, kodwa uxinzelelo lwangaphakathi lwemveliso lukhulu kwaye kulula ukuqhekeka. Ke ngoko kuyacetyiswa ukuba kuphuculwe ukunyibilika ngokunyusa iqondo lobushushu endaweni yoxinzelelo, kunye nokunciphisa ukubakho kokuqhekeka ngokwandisa iqondo lobushushu besifo, ukuphucula ubume bento efayo nasemva konyango. Xa isantya senaliti sisezantsi, isango lityekele ekumiseleni nakwezinye iziphene, iqondo lobushushu ngemilomo yemitha kufuneka ilawulwe ngokwahlukeneyo, ubushushu besikhunta kufuneka bube phezulu, kwaye ukumelana nembaleki kunye nesango kufuneka kube kuncinci.
3. Iimpawu zobuchwephesha bePET PET zinobushushu obumbaxa obuphezulu kunye noluhlu olucekeceke lohlengahlengiso lobushushu bezinto, kodwa lunobushushu obulungileyo emva kokunyibilika, ngenxa yoko ayisebenzi kakuhle, kwaye isixhobo sokulwa nesongezo sihlala sidityaniswa ngemilomo. Amandla oomatshini kunye nokusebenza emva kwenaliti akukho phezulu, kufuneka ngenkqubo yolule kunye nokulungiswa kunokuphucula ukusebenza. Ulawulo oluchanekileyo lobushushu bokufa kukuthintela ukugoba.
Ngenxa yento ebalulekileyo yokusilela, imbaleki eshushu iyacetyiswa. Ukuba iqondo lobushushu lokufa liphezulu, ubumenyemenye bomhlaba buya kuba buthathaka kwaye nokonakaliswa kuya kuba nzima.

I-1 Craze: i-anisotropy yoxinzelelo lwangaphakathi ngexesha lokuzaliswa kunye nokuxinana, kunye noxinzelelo oluveliswe kwicala elimi nkqo, yenza ukuba i-resin iqhubeke iye phezulu, ngelixa ukungahambi okungahambelaniyo kuvelisa ukukhanya kweflash ngesalathiso esahlukileyo sokukhangela. Xa isanda, iintanda zingenzeka kwimveliso.
Iindlela ezoyisayo zezi: ukucoca ukungunda kunye nomgqomo womatshini wenaliti, ukomisa izixhobo ezingafunekiyo ngokwaneleyo, ukwandisa igesi yokukhupha, ukonyusa uxinzelelo lwenaliti kunye noxinzelelo lwangasemva, kunye nokongeza imveliso efanelekileyo. Ukuba izinto zePC zinokufudunyezwa ngaphezulu kwe-160 ° C kangangemizuzu emi-3 ukuya kwemi-5, emva koko inokupholisa ngokwendalo.
2. I-Bubble: Amanzi kunye nezinye iigesi ezikule resin azinakukhutshwa (ngexesha lokuncitshiswa kwesikhunta) okanye "iibhola ezincamathelayo" zenziwa ngenxa yokungoneliseki kokungunda kunye nokuxinana okukhawulezayo komphezulu wokujiya. Iindlela ezoyisayo zibandakanya ukwanda kokukhupha kunye nokoma ngokwaneleyo, ukongeza isango eludongeni lwangasemva, ukonyusa uxinzelelo kunye nesantya, ukunciphisa ukunyibilika kobushushu kunye nokwandisa ixesha lokupholisa.
3. Ukuqaqamba komphezulu womhlaba: ubukhulu becala ngenxa yokurhabaxa okukhulu kwedini, kwelinye icala, ukufuma kwangoko, ukuze intlaka ingabinakho ukukopa imeko yomphezulu wokufa, zonke ezo zinto zenza ukuba umphezulu wediza ungalingani kancinci , kwaye wenze imveliso ilahle isilungiseleli seglosi. Indlela yokoyisa le ngxaki kukonyusa ubushushu obunyibilikayo, ubushushu besikhunta, uxinzelelo lwenaliti kunye nesantya senaliti, kunye nexesha lokupholisa.
4. Ingqushu yenyikima: iji eshinyeneyo eyenziweyo isuka embindini wesango elithe nkqo. Isizathu kukuba i-viscosity ye-melt iphakame kakhulu, izinto ezingaphambili ziye zajija emgodini, emva koko izinto ziqhekeze umphezulu wokujiya, oko kukhokelele kukugqabhuka komphezulu. Iindlela ezoyisayo zezi: ukonyuka koxinzelelo lwenaliti, ixesha lenaliti, ixesha lenaliti kunye nesantya, ukwanda kobushushu besikhunta, ukukhetha imibhobho efanelekileyo kunye nokwanda kwemithombo yokubanda ebandayo.
5. Mhlophe. Halo yenkungu: Inokubangelwa luthuli oluwela kwizinto ezingumoya emoyeni okanye ukufuma okugqithisileyo kwezinto ezingafunekiyo. Iindlela ezoyisayo zezi: ukususa ukungcola komatshini wokubumba inaliti, ukuqinisekisa ukoma okwaneleyo kwezinto zeplastikhi, ukulawula ngokuchanekileyo ukunyibilika kobushushu, ukunyusa ubushushu besikhunta, ukonyusa uxinzelelo lwasemva lwenaliti kunye nokunciphisa umjikelo wenaliti. 6. Umsi omhlophe. Indawo emnyama: Kubangelwa ikakhulu kukubola okanye ukonakala kwentlaka emgqonyeni ebangelwe bubushushu beplastiki kwindawo leyo. Indlela yokoyisa ukunciphisa ubushushu obunyibilikayo kunye nexesha lokuhlala kwezinto zokwenza izinto kumbhobho, kwaye wandise umngxunya wokukhupha.
Inkampani yakwaMestech igxile ekuboneleleni abathengi ngesibane selitha esingabonakaliyo, iimveliso zephaneli yonyango yombane kunye nemveliso yenaliti. Ukuba ufuna oku, nceda unxibelelane nathi. Siyavuya ukukunika ezo nkonzo.
