Ukwethulwa okuningiliziwe kwebhodi le-PTFE

(1) Umbala webhodi umbala wemvelo we-resin.

(2) Ukuthungwa kufanele kufane, nobuso bube bushelelezi, futhi kungabikho zinkinga ezifana nemifantu, amabhamuza, i-delamination, ukulimala kwemishini, omaka bommese, njll.

(3) Kuyaqina ukuqina okufana nefu.

(4) Kuvunyelwe ukungabi nokungcola okungaphezu kokukodwa okungaphezu kokukodwa nobubanzi obungu-0.1-0.5mm futhi kungabi ngaphezu kokukodwa ukungcola okungekhona okwensimbi nobubanzi obungu-0.5-2mm endaweni eyi-10 × 10cm.

(5) Ubuningi bungu-2.1-2.3T / m3.

Izici zebhodi le-PTFE: ukuzinza kwamakhemikhali okuhle kakhulu, ukumelana nokugqwala, ukuqina, ukuthambisa okuphezulu, okungeyona induku, okungewona ubuthi, ukuvimba kukagesi nokukhuthazela okuhle kokulwa nokuguga.

I-polyethylene tetrafluoroethylene plate (i-polyethylene tetrafluoroethylene plate) yokwakhiwa kwephrojekthi yeSichuan Nanchong (izinyathelo zokufaka):

Ukusebenza kokushayisana okuphansi ngokomthwalo. Ngoba ingxenye yokushayisana kweminye imishini ayikulungele ukuthambisa, njengezikhathi lapho igrisi lokuthambisa lizoncibilikiswa ngamakhemikhali awuketshezi bese lihluleka, noma imikhiqizo emkhakheni wezimboni njengokwenza amaphepha, imithi, ukudla, izindwangu, njll. ukugwema ukungcoliswa kukawoyela, okwenza okokugcwalisa kwe-PTFE kube yinto ekahle yokuthambisa kwamafutha (umthwalo oqondile) wezingxenye zemishini. Lokhu kungenxa yokuthi i-coefficient yokungqubuzana kwale nto iphansi phakathi kwezinto eziqinile ezaziwayo. Ukusetshenziswa kwayo okuqondile kufaka phakathi amabombo wemishini yamakhemikhali, imishini yokwenza amaphepha, imishini yezolimo, njengamasongo e-piston, izinkombandlela zamathuluzi womshini, amasongo wokuqondisa; kwezobunjiniyela, isetshenziswa kabanzi njengamabhuloho, imigudu, amapulangwe ophahla lwensimbi, amapayipi amakhulu amakhemikhali namathangi okugcina. I-block sliding block, futhi isetshenziswe njengokuxhaswa kwebhuloho ne-bridge swivel, njll.

I-Polytetrafluoroethylene (PTFE) inokuqina okuhle kwamakhemikhali, ingamelana nawo wonke ama-acid aqinile, ama-alkalis aqinile, nama-oxidants aqinile, futhi ayihlangani nama-solvents ahlukahlukene. I-PTFE inebanga lokushisa elibanzi lokusebenza. Ingasetshenziswa isikhathi eside ku- -180 ℃ ~ 250 ℃ ngaphansi kwengcindezi ejwayelekile. Ngemuva kokwelapha okungu-1000h ku-250 ℃, izakhiwo zayo zomshini zizoshintsha kancane. I-PTFE inesici esiphansi kakhulu sokungqubuzana, iyinto enhle yokulwa nokungqubuzana, okokuzigcobayo, ukulingana kwayo okungama-static kuncane kune-coefficient enamandla yokungqubuzana, ngakho-ke kunezinzuzo zokumelana okuphansi kokuqala nokusebenza kahle lapho kusetshenziselwa ukwenza amabombo. Ngenxa yokuthi i-PTFE ayisebenzi polar, iyamelana nokushisa futhi ayimunce amanzi, futhi iyinto enhle kakhulu yokuvikela ugesi. Ibuye ibe nokumelana nokuguga okuhle kakhulu, okunganamatheli nokungashisi. Umehluko phakathi kwesitebhisi se-Duoyao brand stair ekhethekile se-PTFE sokubuyisa impahla kanye nezinto ezintsha: ngemuva kokuthi impahla entsha icutshungulwe ibe ngumkhiqizo, izinto ezizungeze itheku leglue kumkhiqizo zingangezwa entweni entsha ngemuva kokuchotshozwa. Ikhadi lesibili: into ukusebenza kwayo okungeke kuhlangabezane nezimfuneko ezicini ezithile. Izinto ezenziwe kabusha: kabusha i-granulation ngemuva kokuphinda kusetshenziswe kabusha. Umbhobho ikakhulukazi ubhekisa engxenyeni esele yezingxenye zomjovo ezibunjiwe, eziphukile, okusho ukuthi, into ephukile, njengokungathi ingxenye esele yokudla iyadliwa. Izinto ezenziwe kabusha zibhekisa ezintweni ezenziwe kabusha nezisetshenziswe. Kungaba yi-granulation ekhoneni noma i-granulation yemfucuza, ebhekisa ezintweni eziphinde zenziwa kabusha zaphinde zenziwa granulated ngomshini. Ukuphinda kusetshenziswe kabusha kubizwa ngokuthi izinto ezenziwe kabusha, futhi ukuphinda kusetshenziswe kabusha izikhathi ze-N kubizwa nangokuthi izinto ezenziwe kabusha.

Ungayilungisa kanjani ipuleti ye-fluorine? Yini elungisiwe? Izinyathelo zokuphepha zendlela yokwakha! Isitebhisi PTFE indlela yokwakha ibhodi M4 ngezikulufo zisebenza kuphela ukulungisa ibhodi le-polyethylene PTFE, awukho umehluko phakathi kokufakwa ngaphakathi noma kokufakwa ngemuva, ikakhulukazi ngokuya ngokuthi iyiphi indlela elula kakhulu yokwakha esizeni. Imvamisa, izimbobo zesikulufu se-M4 ebhodini le-polyethylene PTFE zingabhalwa kalula ngebhodi ejwayelekile kagesi.
