Iindaba

Cacisa isikrufu esinye se-granulation ngolu hlobo: i-feedstock, ukulungiswa okufunekayo kwe-nyibilika, umthwalo wokukhupha umoya, umsebenzi wokuxuba, ukuxhathisa ukuhluzwa kunye nendlela yokugaya. Xela ukuba ukutya kuyipellet ecocekileyo, umgubo, i-agglomerate, i-flake ehlanjiweyo okanye umsinga ohlaziyiweyo. Ukubonelela ngenqanaba le-resin, imeko yovavanyo lwe-MFR, umswakama, ungcoliseko, isigcwalisi, ukukhutshwa okujoliswe kuko, i-motor, i-rpm, ilungiselelo le-vacuum kunye neempawu zangoku. Isikrufu sinokuthi siyilwe sijikeleze ifestile yemathiriyeli yokwenyani endaweni yedayamitha yegama.

Khetha i-screw yokuvuthela ifilimu kulo myalelo: i-resin kunye nokuqulunqwa, ifilimu egqityiweyo kunye nesakhiwo somaleko, umsebenzi womgca, emva koko ijiyometri ye-screw kunye nenkqubo yomhlaba. Buza ibakala elichanekileyo leresin kunye nemeko yovavanyo lokunyibilika, hayi kuphela i-“LDPE,” “LLDPE” okanye “i-HDPE.” Rekhoda umlinganiselo wokudityaniswa, izongezo, umxholo ohlaziyiweyo, imveliso, isantya se-screw, i-motor, die, ububanzi befilimu kunye noluhlu lobuninzi. Kuphela emva koko uthathe isigqibo malunga nedayamitha, i-L / D, ubunzulu bokutya, iprofayili yokunyibilika, icandelo lokulinganisa kunye nokuba umqobo okanye icandelo lokuxuba lifanelekile.

Ukulinganisa ukunxiba njengesibini esekwe kwindawo, hayi njengedayamitha yesikrufu esinye. Phawula izikhululo ze-axial ngokutya, ucinezelo kunye neendawo zokulinganisa iimitha. Kwisikhululo ngasinye, rekhoda isikhovu sokubhabha ngaphandle kwedayamitha kunye nombhobho ongaphakathi kwidayamitha kwiindlela ezininzi zee-angile. Emva koko ubale i-diametral kunye ne-radial clearance ngokwahlukeneyo. Thelekisa imephu nomzobo ovunyiweyo wokuqala okanye ireferensi yoyilo ekuvunyelwene ngayo ngokucacileyo. Ukuba unamalungu agugileyo kuphela, bhala iziphumo njengedatha yemeko. Ungazibonisi njengemilinganiselo yokuqala.

Buyisela isikrufu kuphela xa kulinganisiwe umbhobho, ukungqukuva, ubume bomphezulu kunye nolungelelwaniso luhlala lufanelekile kwisikrufu esitsha esicetywayo. Faka indawo yomibini indawo xa umphanda wandiswa, umbhoxo, uhlanjwe ekuhlaleni, ubolekwe okanye udleke ngokwaneleyo ukuze isikrufu esitsha siqhubeke sisebenza ngokugqith emgceni okanye ngokungalinganiyo. Ukuba awunayo imilinganiselo yokukruqula, sukuqikelela. Indawo yethu yefektri ilula: i-quotation-screw-only quotation ayifanele iphathwe njengengcebiso epheleleyo yobugcisa de kube imeko yombhobho ihlolwe.

Khetha isikrufu esiqhelekileyo somxhesho ozinzileyo, ofanayo wepellet kunye nemveliso ephakathi xa umsebenzi olula ungowona uphambili. Khetha isikrufu somqobo xa umgca ufuna ukunyibilika okupheleleyo kunye nemveliso ezinzileyo kumazinga aphezulu, ngakumbi kwi-PE kunye ne-PP. Khetha isikrufu sokuxuba xa unyibilika-ubushushu obufanayo, ukuhanjiswa kombala okanye ukusasazwa okongeziweyo yeyona ngxaki iphambili. Umqobo kunye nemisebenzi yokuxuba ayihambelani. I-aluminiyam-iplastiki yeplasitiki yepaneli ye-Nanhaiya i-screw enye, umzekelo, isebenzisa icandelo lokuxuba uhlobo lomqobo ukuxhasa ukunyibilika, ukunyibilika okufanayo kunye nokuhanjiswa kwemibala kunye ne-flame retardants.

I-screw extruder enye iyanyuka xa imathiriyeli ihamba emgceni iyeka ukuzinza. Imithombo eqhelekileyo iquka ukondla okungaguqukiyo, ukuguquguquka kwesantya se-screw-speed, ubushushu bombhobho obungazinzanga, ukunyibilika okungagqibekanga okanye okungazinzanga, ukutshintshwa kwesikrini okanye uthintelo lokufa, ukunxitywa kwe-screw-and-barrel, kunye nokuhluka kwesantya esisezantsi. Rekhoda uxinzelelo lokunyibilika, isantya semoto, isantya se-screw, ubushushu bendawo, isantya sokutya kunye nesantya esisezantsi kumda wexesha ngaphambi kokutshintsha useto. Ukuba uxinzelelo kunye nemveliso zihamba kunye, phanda i-extruder kunye nendlela yokuhamba. Ukuba iintsingiselo ze-extruder zihlala zizinzile ngelixa imveliso iguquka, qala ngokufa, ukupholisa, ukucoca, ukukhupha okanye ukuvuthela.
