PVC foaming zvigadzirwa zvinoda kuwedzerwa zvakasiyana-siyana zvinowedzera. Nhasi, rega Qingdao Sainuo ope wakisi mugadziri atore iwe kuti unzwisise kusaenzana pakati pezvimwe zvinowedzera!

1. Stabilizer
Lead salt stabilizer uye calcium zinc stabilizer ndiyo inonyanya kushandiswa kugadzikana muPVC foam products. Nekuwedzera uye zvakanyanya kuomarara zvinodiwa zvekuchengetedzwa kwezvakatipoteredza uye kudhura kwekuita kwecalcium zinc stabilizer, kushandiswa kwecalcium zinc stabilizer kwakatanga kuwedzera uye zvakanyanya.
Insufficient stabilizer, yellowing of board surface, high brittleness of paste uye zvigadzirwa, kuderedzwa simba uye kuderera kwefuro rate;
Kana pane zvakawanda zvakadzikamisa, iyo inoputika inoparara kare, gasi rinoputika kubva mugomba rekudyisa uye gomba rekutsvaira, uye chimiro chemhango chichatsemura tendon kana kuderedza zviratidzo;
2. Mafuta
ekunze anonyanya kushandiswa pazvigadzirwa zvine furo anosanganisira wakisi yeparafini uyePe wakisi . Parafini wakisi iri nyore kudonha, saka PE wakisi inowanzoshandiswa.

Kutsvedza kwekunze hakuna kukwana, tembiricha munzvimbo 4 ne5 yeextruder yakaoma kudzora, uye zviri nyore kudarika tembiricha. Pane blister, blisters, yellowing uye rough plate pamusoro peplate pamusoro; Friction shear kupisa kunowedzera, zvichikonzera kuora kwezvinhu, kutsvuka kweplate pamusoro uye paste;
Kuwedzeredza kwekunze kutsvedza uye kushata kwepurasitiki kunotungamirira mukuyera mugomba remuvhu uye kunaya pamusoro pechigadzirwa, icho chinowanzoita leucorrhea, kusaenzana kwemadziro ukobvu uye kusaenzana nekudzoka shure kwekufamba kwezvimwe zviratidzo pamusoro;
3. Internal lubricant
Kusakwana mukati lubrication, varombo zvinhu kupararira, kusaenzana plasticization, zvakaoma kudzora chigadzirwa ukobvu, gobvu furo bhodhi pakati uye nhete kumativi ose, leucorrhea, adhesion kuti chakuvhe mhango uye womunharaunda overheating kunogonawo kuitika;
Kuwedzera kwemafuta emukati, brittle foaming zvigadzirwa, kuderedzwa kupisa kwekudzivirira, uye kuchinjika kune yekunze lubrication pasi peimwe tembiricha uye kunyunguduka kunyungudika, zvichikonzera kudzikamisa kusingaenzaniswi;
Kusakwana kwemukati nekunze kwekuzora, yakakwira melt viscosity, yakakwira plasticizing torque, yakanyungudika yakanyunguduka madziro adhesion, yero decomposition line pamusoro pezvinhu, kushata kwepamusoro uye kuderedzwa kwemakanika echigadzirwa;
Iyo yemukati uye yekunze lubrication yakawandisa, iyo plasticizing torque idiki, uye kunyunguduka kwepurasitiki kuri pachena kuti hakuna kukwana. Kunyange zvazvo chigadzirwa chacho chine kunaka kwakanaka, iyo yekumanikidzika yekunamatira haina kunaka, iyo inokanganisa zvakanyanya michina yechigadzirwa;
Iko kune kuderera kwemukati kwemukati uye kuwedzera kwekunze kwekuzora, nguva yepurasitiki iri pachena yakareba, torque yeplasticizing yakaderedzwa, chigadzirwa chakaoma kuumba uye chinova brittle;
Kuwedzera kwemukati mafuta, kushomeka kwekunze kwekuzora, kupfupika kweplasticizing nguva, yakakomba madziro inonamira, ipfupi kupisa kwekushisa nguva, uye kuora mitsetse yero pachigadzirwa;
4. Calcium upfu Karusiyamu
chiedza chine chidimbu chinokwana 1200 mesh chinowanzoenderana nezvigadzirwa zvinopupa. Calcium poda iri nyore kutora unyoro uye kugadzira mabhuru uye kupenga pamusoro pezvigadzirwa, izvo zvinokanganisa chitarisiko uye chimiro chemuviri. Nokudaro, teerera kuchengetedza munguva yekunaya.
Kana iyo particle size ye calcium carbonate yakakura kwazvo, zviri nyore kusanganisa zvisina kuenzana, nguva yepurasitiki yekusanganiswa inononoka, uye screw torque yakaderera;
Kana iyo particle size ye calcium carbonate yakanyanya kuduku, zviri nyore kuunganidza uye kuchinja kubva kune zviduku zvishoma kusvika kune zvimedu zvakakura, izvo zvakafanana nemigumisiro yezvimedu zvakakura;
Kana chiyero che calcium carbonate chiri chidiki kwazvo, sero rinoshaya musimboti, nhamba yesero inoderera uye furo rinoderera;
Apo chiyero che calcium carbonate chakanyanya kukwirira, hukama hwemukati we resin muzvikamu zvinoderera, simba rekunyunguduka rinoderera, uye chikamu cheplate chiri nyore kuputsa mabhubhu;

5. Foaming regulator
Foaming regulator kazhinji inoreva acrylate processing additives ine viscosity pamusoro 10. Huni epurasitiki inopupuma zvigadzirwa senge ecological huni uye madziro ekudzivirira bhodhi anowanzo shandisa mhando nekukurumidza plasticization. Foaming regulator ine inononoka plasticization uye yakanyanya kunyungudika simba rinowanzo shandiswa kupupa bhodhi, kunyanya kabati bhodhi.
Iyo foam regulator haina kukwana, simba rekunyunguduka rakashata, sero haina kuenzana, sero richaonekwa muchikamu uye density ichawedzera;
Kune akawanda akawandisa madhiraivha anopupuma, simba rekunyunguduka rakakurisa, mabhubhu ari mukunyunguduka haakwanise kuwedzera, density yechigadzirwa yakakwira, uye dhizaini inotarisana nemitsara yewavy, kukanganisa uye deformation;
6. Foaming agent
Hurukuro hukuru hwehuputi hunopupa i AC yero inopupuma ne NC jena inopupuma furo. AC inoburitsa kupisa kwakawanda panguva yekuora, zvichikonzera kutsvuka kwezvigadzirwa uye kunhuhwirira kudiki kweammonia panguva yekuora; NC inotora kupisa panguva yekuora, uye kuora hakuna kunaka. Naizvozvo, iwo marudzi maviri ezvigadzirwa zvefuro anowanzo shandiswa mukubatana.
Huwandu hwehuputi hwemumiriri husina kukwana, chiyero chinopupuma chakaderera, chigadzirwa chine mabhuru mashoma uye kukwirira kwakawanda;
Kana yakawandisa furo agent inoshandiswa, simba rekunyunguduka richave rakaderera, chigadzirwa chacho chakaoma kuumba, uye chikamu chefoam board chiri nyore kugadzira mabhubhu; Kupfuura humwe huwandu, density yechigadzirwa inova yakakura;
Yellow foaming agent yakawanda, furo jena ishoma, uye mabhuru makuru uye akatenderera ari nyore kuoneka muchikamu.
Naizvozvo, iyo dosage yeakasiyana ekuwedzera ine dhigirii uye hukama hwekudzora hukama. Mukudzidzira kugadzira, isu tinofanirwa kuenda kuburikidza nekudzokororwa bvunzo, kupa kutamba kwakazara kune yekubatanidza maitiro ezvakasiyana zvigadzirwa, kutsvaga yakanakisa chiyero poindi, kunyatso vandudza simba rekunyunguduka uye kunyatsobuda furo, uye kurebesa nguva yekutanga.
