PTFE MOLECULE CF2 Yuniti yakarongedzwa muchimiro chengarava, nekuda kweFluorine Atom radius yakakura kupfuura iyo hydrogen yekuyambuka kutarisisa, asi kuumbwa kweteni yechiHexiced, fluorine maatomu Dhavhara kanenge ka dzose pamusoro penzvimbo yePolymer, kuumbwa kwekuvhara kuitira kuti idiki yeiyo hydrogen yakanyanya kuoma kupinda muC - f Bond. Panguva imwecheteyo, iyo Fluorine atomu ine yakasimba emagetsi (4. 0), iyo ATOMIC radius idiki (0.35nm), f hutsinye (f ipfupi (0. 138nm), uye simba reC - F yakakwira (452kj / mol), saka zvakaoma kwazvo kutyora iyo c - F. Aya maitiro aya anoratidza zvakasiyana siyana zveP TF E.
Nei isingakwanise kuremerwa?
Zvikonzero zvikuru nei ptfe ptletetrafluorohlene haukwanise kuumbwa zvinosanganisira nzvimbo yayo yakakwirira yekunyungudika, hombe yekuvesa kwekunyungudika, uye chimiro chakasimba chichikanganisa mumamiriro ezvinhu akaumbwa. Izvi zvivakwa zvinoita kuti PTFE isingafanirwe kuita macomputer epurasitiki kuumba maitiro akadai se jekiseni kuumbwa.
Yakanyanya Rolling Point: PTFE ine inonyungudika yenyaya yeanenge 327 ° CL uye yayo yekunyungudutsa mavheti madhiza akati wandei ehukuru kupfuura ayo ezvakajairwa errmoplastics. Izvi zvinoreva kuti pakupisa kwakanyanya, ptfe inoyerera zvakanyanya uye yakaoma kupisa kuburikidza neyekunyudza molding muchina uye wobva wapinza muumbi kuti ugadzire chimiro chaunoda.
Shape kugadzikana mumamiriro ezvinhu akanyungudutswa: Munyika yakanyungudutswa, ptfe inokwanisa kuchengetedza chimiro chayo chepakutanga, chakafanana neye Jelly State isingagoni kuyerera. Hunhu uhwu hunoita kuti PTFE isingakwanisi kuumbwa ne jekiseni kuumbwa semamwe maTirmoplastics.
Mukuwedzera, kugadzirisa kwaPTFE pakugadziriswa kwemukati hakusi kwekuwedzera kwetsetse nekuwedzera kwekushisa uye kushanduka-kuchinjika uye kuchitonhora kuchinjika, kunowedzera kushanduka kwayo, izvo zvinodzikira zvinoshandiswa mukuumbwa.
Kuumba maitiro ePolytetraFluorohyle
Ptfe crystallization yekunyungudza pfungwa ye327 Mukuwedzera, ptfe ine yakasimba solvent kuramba. Naizvozvo, hazvigone kushandisa nzira yekunyungudika, kazhinji hazvigone kushandisa nzira yekunyungudika, kazhinji kugadzirwa kwezvigadzirwa zvaro kunogona kungoita sekugadziriswa kwemasimbi uye ceramics, iyo yekutanga poda combicction, uye wozotadza nekugadzirisa uye maitiro ekugadzirisa, kana Kuburikidza nekuwedzera kuumbwa, isolbaric kuumbwa, kuunganidza kuumbwa uye kuumbwa nekuumbwa uye dzimwe nzira dzekugadzirisa.
1, kuumbwa
Kudzvinyirira kuumbwa kuri ptfe parizvino ndiyo inonyanya kushandiswa kuumbwa maitiro. Kuumbwa kwemaitiro kune imwe huwandu hwekuumbwa neyakagadzirwa zvinhu (poda, granules, mbichana, etc.) mune simbi yekuumbwa, pane imwe tembiricha, kudzvinyirira nzira yekunyima.
2, Hydraulic Moding nzira
Hydraulic nzira, zvakare inozivikanwa seyakaenzana nzira, ndiyo PTFer Resin yakawedzerwa kuhombodo yerubhi uye yakabviswa mumvura yerabha (inowanzoshandiswa mvura), zvichikonzera kumanikidzwa kubhegi kune iyo mall wall kuwedzera, compaction yeiyo resin uye kuve chigadzirwa chisati chave chakaumbwa.
3, pushira kuumbwa
Sundidzira zvakare seaneta Extrussion kuumbwa, 20-30 mesh sieve kupararira uye organc emafuta, solvent yemafuta, eth. Yakakura-yakakomberedzwa yakapetwa yakareruka isina chinhu, uye wobva waiswa muzvisvinu zvekumanikidza mune pfupi, pasi pekupisa kwePlunger kusundira kuumbwa. Mushure mekuoma muna 360 ~ 380C tembiricha muchiputira, kutonhora kuti uwane yakasimba push-tinya tube, tsvimbo nezvimwe zvigadzirwa. Push Zvigadzirwa zvinogumira kune iyo Diameter ye 16mm pazasi yetsvimbo uye kurira kwemadziro kwe 3mm pazasi pehubhu uye zvichingodaro.
4, screw inoparara kuumbwa
PTFE POWODS SCREW LETSUDER YAKASHURE NEZVINHU ZVINOGONESA, AIVA NEMAHARA Kuiswa pasi pechiitiko chekutsiva kwehasha kunogadzirwa nekupisa uye zvinyorwa zvishoma kunze kwekudziya kuitira kuti zvinyungunuke. Iyo PTFE SCREW LETTE PAMUSORO PENYAYA YOKUSHANDA, Kuti Mhedzisiro Yemusoro Wemusoro, Yakadzika Musoro, uyezve mumuromo weMold Sintering , kutonhora, uye nerubatsiro rwemavhosva-yekumanikidza mudziyo kupa kudzvinyirira kuumbwa, kuzadzisa chinangwa chekuenderera mberi.
5, plunger Extrusion kuumbwa
Plunger Extrussion kuumbwa kwekugadzirisa mapurasitiki, plastics yekugadzirisa ichave nzira yekare, nekuti kubuda kwemidziyo yakadai seplastics, vanhu vakatanga kushandisa nzira yekuita mapuranga. Plunger Extruder ptfe is the lesin yakamanikidzwa mumuromo, zvekuti iyo plunger yekudzoreredza kufamba, ichamanikidzwa mune zvigadzirwa zvisingaverengeki. Plungeer inodzokera kumashure uye inogadzira zvikamu zvakawanda zvezvinofungisisa mufe.
