Ha ho bapisoa le lihlahisoa tse ling tsa polasetiki tse extruded, tlhahiso ea SUZHOU SUPXTECH ea letlalo le tlaase PVC lihlahisoa tsa polasetiki ha e hloke feela polasetiki e ntle tlas'a khatello e itseng ea ho qhibiliha, empa hape e na le litlhoko tse lumellanang tsa tekheniki bakeng sa boholo, bongata le ho tšoana ha masoba a foam, hammoho le botenya, ho thatafala, ho kganya le ho fela ha letlalo.Boleng ba 'mele o phoroselang ha bo amane feela le foromo le lisebelisoa tse tala, empa hape bo ameha ka ho toba le ho thibeloa ke ts'ebetso ea ho kuta ea extruder screw, melt pressure, mocheso, extrusion (traction) lebelo, lekhalo la molomo oa hlobo, lekhalo la hlobo, ho pholisa. mocheso oa metsi le lintlha tse ling.Ka hona, ha ho bapisoa le lihlahisoa tse ling tsa polasetiki tse extruded, lihlahisoa tsa polasetiki tsa foam tsa letlalo li na le bothata bo itseng ba tekheniki, ho tloha ts'ebetsong le khopolong ho na le mathata a mangata a sa rarolloang a lokelang ho ithuta le ho rarolla mathata a indasteri.
1, theknoloji ea tlhahiso ea pampiri ea polasetiki ea PVC ea letlalo le litšobotsi
Bothata ba tekheniki tlhahisong ea lihlahisoa tsa polasetiki tsa PVC tse phophomang letlalo bo foaming.Ho foaming ke phello ea ho eketseha le ho atolosoa ha viscosity ea ho qhibiliha, khatello ea khase e hlahisoang ke moemeli oa foaming le khatello ea sepakapaka.
Mokhoa oa ho ntša lekobo ka kakaretso o feta mekhahlelo e meraro:
(1) Foaming khase e qhibiliha ka plasticized junifomo motsoako qhibiliha ka mocheso itseng le khatello ea extruder le fihla saturation mmuso ho theha bubble konokono;
(2) The qhibiliha e extruded ho tloha shoa, 'me ka ho lokolloa khatello ea, le supersaturated qhibiliha likhase nucleates, atolosa le precipitates, ho etsa junifomo le teteaneng bubble masoba lekhalong la formwork;
(3) Tlas'a phello e pholileng ea sesebelisoa sa ho bōpa, lihlahisoa tse foaming li tiisitsoe le ho bōptjoa.Boleng bo botle bo botle ba letlalo PVC lihlahisoa tsa polasetiki li na le litšobotsi tsa likoti tse ngata le tse teteaneng tsa bubble, tse nyane le tse ts'oanang, lekhalo le botenya li fihlela litlhoko, ponahalo e boreleli, boima bo phahameng le khanya.
2, letlalo foam PVC polasetiki boto boleng lintlha
Lintho tse ka sehloohong tse tala tse amang ka ho toba boleng ba sebopeho sa bubble ea polasetiki ke sesebelisoa sa foaming le harmonizer ea foaming.Lisebelisoa tse tala tse kang stabilizer, lubricant, calcium carbonate le taolo ea ts'ebetso ea extrusion li ka khothaletsa le ho hokahanya boleng bo phophomang ho isa bohōleng bo itseng.Hobane mocheso oa polasetiki oa ho qhibiliha ts'ebetsong ea extrusion ea lihlahisoa tse phophomang e tlameha ho ba tlase hanyane ho feta mocheso oa ho bola oa ntho e phoroselang, ho theola tekanyo e tloaelehileng ea polymerization ea resin ea PVC, ho theola mocheso o hlokahalang bakeng sa ho qhibiliha polasetiki.Ho fumana lihlahisoa tsa polasetiki tse foamed ka botlalo, viscosity ea resin ha ea lokela ho ba holimo haholo.Ka nako e ts'oanang, ha e bapisoa le lihlahisoa tse ling tse foaming, hobane karolo ea sefapano sa ho etsa lakane e pharaletseng, ho tloha hloohong ea extrusion ho ea ka molomong oa shoa ho ajoa ka bophara ba hoo e ka bang 1.3m, e le ho thusa ho hasana le ho atolosoa ha li-bubble. , khatello ea karolo eohle ea sefapano sa lakane e lokela ho hokahanngoa, metsi a qhibilihang a phahame, 'me boima ba molek'hule ba resin hangata bo nyane.Joalo ka SC-7 kapa SC-8 mokhoa oa ho fanyeha resin e hlephileng e loketse haholoanyane.SUZHOU SUPXTECH
