Iindaba

I-masterbatch yesiliconeluhlobo lolongezo kwishishini lerabha kunye neplastiki. Ubuchwepheshe obuphambili kwicandelo lezongezo ze-silicone kukusetyenziswa kwe-silicone polymer ye-ultra-high molecular weight (UHMW) (PDMS) kwiiresini ezahlukeneyo ze-thermoplastic, ezifana ne-LDPE, i-EVA, i-TPEE, i-HDPE, i-ABS, i-PP, i-PA6, i-PET, i-TPU, i-HIPS, i-POM, i-LLDPE, i-PC, i-SAN, njl. Kwaye njengeepellets ukuze kube lula ukongeza olongezo ngqo kwi-thermoplastic ngexesha lokucubungula. kudibanisa ukucubungula okugqwesileyo ngexabiso elifikelelekayo. I-silicone masterbatch kulula ukuyitya, okanye ukuyixuba, kwiiplastiki ngexesha lokudibanisa, ukukhupha, okanye ukubumba ngenaliti. Ingcono kune-oyile ye-wax yendabuko kunye nezinye izongezo ekuphuculeni ukutyibilika ngexesha lokuvelisa. Ke ngoko, iiprosesa zeplastiki zikhetha ukuzisebenzisa kwimveliso.

Iindima zeI-Silicone Masterbatch additiveekuPhuculeni ukuCwangciswa kwePlastiki

I-silicone masterbatch yenye yezona ndlela zidumileyo zokukhetha abaprosesa kwi-plastic processing kunye nokuphucula umgangatho womphezulu. Njengohlobo lwe-super lubricant. Inemisebenzi ephambili elandelayo xa isetyenziswa kwi-thermoplastic resin:

A. Ukuphucula ukuhamba kwe-resin kunye nokucubungula;

Ukuzaliswa kwesikhunta okungcono kunye neempawu zokukhulula isikhunta

Nciphisa i-torque ye-extrude kwaye uphucule izinga le-extrusion;

B. Iphucula iipropati zomphezulu we-resin

Phucula ukugqitywa komphezulu weplastiki, iqondo eligudileyo, kwaye unciphise i-coefficient yokungqubana kwesikhumba, Phucula ukumelana nokuguguleka kunye nokumelana nokukrwela;

Kwaye i-silicone masterbatch inozinzo oluhle lobushushu (ubushushu bokubola kobushushu bumalunga ne-430 ℃ kwi-nitrogen) kwaye ayifuduki;

Ukhuseleko lokusingqongileyo;

Unxibelelwano olukhuselekileyo nokutya.

Kufuneka siqaphele ukuba zonke ii-silicone masterbatches ziphantsi kuka-A no-B (amanqaku amabini angentla esiwadwelisileyo) kodwa azingomanqaku amabini azimeleyo kodwa

ziyancedisana, kwaye zihlobene kakhulu.

Impembelelo kwiimveliso zokugqibela

Ngenxa yeempawu zesakhiwo se-molecular se-siloxane, idosi incinci kakhulu ngoko ke iyonke phantse akukho ziphumo kwipropathi yoomatshini yeemveliso zokugqibela. Ngokubanzi, ngaphandle kokwandiswa kunye namandla empembelelo kuya kwanda kancinci, ngaphandle kweziphumo kwezinye iipropathi zoomatshini. Kwidosi enkulu, inempembelelo yokusebenzisana kunye neearhente ezithintela ilangatye.

Ngenxa yokusebenza kwayo okugqwesileyo kukumelana nobushushu obuphezulu nobuphantsi, ayizukuba namiphumo mibi kukumelana nobushushu obuphezulu nobuphantsi kweemveliso zokugqibela. Ngelixa ukuhamba kwe-resin, ukucubungula, kunye neempawu zomphezulu kuya kuphucuka ngokucacileyo kwaye i-COF iya kuncitshiswa.

Indlela yokusebenza

Ii-masterbatches zeSiliconeZii-polysiloxane ezinobunzima obuphezulu kakhulu ezisasazeke kwiiresini ezahlukeneyo zokuthwala eziluhlobo lomsebenzi we-masterbatch. Xa ubunzima be-molecular buphezulu kakhuluii-masterbatches ze-siliconezongezwa kwiiplastiki ngenxa yokuba azinazo ii-polar kwaye ngenxa yamandla aphantsi omphezulu, zinomkhwa wokufudukela kumphezulu weplastiki ngexesha lenkqubo yokunyibilika; ngelixa, ekubeni inobunzima obukhulu beemolekyuli, ayinakuphuma ngokupheleleyo. Ngoko ke siyibiza ngokuba yimvisiswano kunye nobunye phakathi kokufuduka kunye nokungafuduki. Ngenxa yale mpawu, umaleko wokuthambisa onamandla owenziwe phakathi komphezulu weplastiki kunye nesikrufu.

Njengoko ukucubungula kuqhubeka, olu layer lokuthambisa luhlala lususwa kwaye lwenziwa. Ngoko ke ukuhamba kwe-resin kunye nokucubungula kuyaphucuka rhoqo kwaye kunciphisa umbane, i-torque yezixhobo kunye nokuphucula imveliso. Emva kokucubungula i-twin-screw, ii-silicone masterbatches ziya kusasazwa ngokulinganayo kwiiplastiki kwaye zenze isuntswana yeoyile eli-1 ukuya kwi-2-micron phantsi kwe-microscope, ezo suntswana yeoyile ziya kubonelela iimveliso ngenkangeleko engcono, imvakalelo entle yesandla, i-COF ephantsi, kunye nokukrala okukhulu kunye nokumelana nokukrwela.

Ukusuka kumfanekiso singabona ukuba i-silicone iya kuba ngamasuntswana amancinci emva kokuba isasazeke kwiiplastiki, into enye ekufuneka siyikhankanye kukuba ukusasazeka yeyona nto iphambili kwi-silicone masterbatches, okukhona amasuntswana emancinci, kokukhona isasazwa ngokulinganayo, kokukhona siya kufumana iziphumo ezingcono.
