I-Jiangsu Aokai New Materials, umenzi oqeqeshiweyo we-PTFE kunye neemveliso ze-fluoroplastic, wabelana ngeendlela zokukhetha ze-PTFE tape yobushushu obuphezulu bokudiliza kunye ne-anti-stick scenarios kwisixhobo sokubumba inaliti.
I. UKhetho oluSekwe kwiqondo lobushushu: Gxininisa ekuxhathiseni ubushushu kuMaleko wokuncamathelisa kunye neSubstrate.
Iteyiphu ye-PTFE inamacandelo amabini: i-substrate (ngokuqhelekileyo ilaphu le-fiberglass elatyiswe nge-PTFE) kunye ne-adhesive exhasayo. I-adhesive layer idla ngokuba yi-bottleneck yokusebenza.
1. Ubushushu bokusebenza obuqhubekayo ≤ 260°C (Iiplastiki ngokubanzi & iiplastiki zobunjineli ezingaphelelanga)
Izinto ezisebenzayo: i-PE, i-PP, i-PS, i-ABS, i-PVC ethambileyo, i-EVA, kunye ne-PA, i-PBT kunye nezinye izinto ezicutshungulwa kwiindawo ezisezantsi zokushisa. Ukhetho olucetyiswayo: I-fiberglass eqhelekileyo eyomeleziweyo ye-PTFE tape kunye ne-silicone i-adhesive-sensitive adhesive (PSA). Ubukhulu obucetywayo: 0.13 mm okanye 0.18 mm, ukuhambelana nokuhambelana kunye nokuqina kwenkonzo. Amanqaku aphambili: Olu lolona luhlu lusebenzayo lwe-PTFE tape, ebonisa uzinzo olugqwesileyo lweekhemikhali kunye nokukhulula ukusebenza.
2. Ubushushu bokusebenza obuqhubekayo 260°C ~ 300°C (Iiplastiki zobunjineli zobushushu obuphezulu)
Izinto ezisebenzayo: I-PC, i-PA66, i-POM, i-PET, i-PPA ephezulu yokushisa, i-PPO elungisiweyo kunye nezinye iifom ze-injection eziphezulu. Ukhetho olucetyiswayo: I-Fiberglass PTFE tape eyenziwe nge-adhesive ye-silicone echasene nobushushu obuphezulu. I-adhesive ye-silicone eqhelekileyo iya kuguga ngokukhawuleza, ilahlekelwe yi-tackiness kwaye ishiye iintsalela phantsi kolu luhlu lobushushu. Ubukhulu obucetywayo: 0.18 mm okanye 0.25 mm. I-adhesive etyebileyo kunye ne-substrate layers ihambisa ngcono i-thermal buffering kunye nokumelana nokunxiba. Ukuqinisekiswa okubalulekileyo: Cacisa iinkqubo zokubambelela kunye nokumelana nokushisa kwexesha elide ngaphezu kwe-280 ° C kubaxhasi, kwaye uqinisekise ukuba i-adhesive iya kungcolisa i-molds phantsi kobushushu obuphezulu.
3. Ubushushu beqondo eliphezulu ngoko nangoko 300°C ~ 400°C (Iiplastiki ezikhethekileyo zobushushu obuphezulu okanye iindawo ezishushu zendawo)
Izinto ezisetyenziswayo: I-PEEK, i-LCP, i-PPS, i-PEI, ifumaneka ikakhulu kufuphi nemibhobho ye-runner eshushu kunye neentloko zokufa ze-extrusion. Isilumkiso soKhetho: Akukho ncamatheliyo ethembekileyo yoxinzelelo olunokumelana nolu hlobo lobushushu. Nayiphi na iteyiphu ye-PTFE encamathelayo iya kusilela ngoko nangoko, i-carbonize kwaye ingcolise iimveliso ezigqityiweyo. Izisombululo ezizezinye:
1. Ilaphu le-PTFE ye-fiberglass engancamathiseliyo, ilungiswe ngoomatshini ngokusebenzisa iifreyimu ezibambayo zokubumba, imicu okanye izinto zokuncamathelisa ezinobushushu obuphezulu (izinto ezincamathelayo ezingavaniyo uxinzelelo ezifana nezitywini zesilicone).
2. Iteyiphu yefilimu ye-PFA efusible ngokupheleleyo, encanyathiselwe kwindawo yokungunda nge-welding yomoya oshushu. Imelana ne-260 ° C eqhubekayo kunye nexesha elifutshane lokubonakaliswa kwe-300 ° C, kodwa ayikwazi ukutshintshwa ngokuguquguqukayo njengeteyiphu yokuzincamathela. Isindululo esisesinye esilungiselelweyo: Kwiimeko ezinjalo zobushushu obuphezulu, i-mold PTFE yokwaleka okanye i-nano ceramic high-temperature coating ende iyacetyiswa.
II. UKhetho oluSekwe kwiPropati yeMathiriyeli: Ukuchasana nokuNxitywa komdlalo, ukuxhathisa ukuMhlwa kunye neeMfuno zokuKhupha
Iimpawu ezibonakalayo kunye neekhemikhali zeplastiki etyhidiweyo zigqiba ukusebenza okufunekayo kwendawo kunye namandla okwakhiwa kwe-tape.
1. Iimathiriyeli ezibukhali kakhulu / ezithandwa ngundo
Izinto ezimele: i-EVA, i-adhesive eshushu enyibilikayo, i-TPE, i-TPU, amabakala athile e-PP alungisiweyo. Amanqaku aphambili okukhetha: Khetha iteyiphu ephezulu enomxholo ophezulu we-PTFE kunye neengubo ezixineneyo. Beka kuqala iteyiphu yefilimu ye-PTFE ecocekileyo (ngaphandle kokuqinisa i-fiberglass, amandla aphantsi, afanelekele kuphela iindawo ezinoxinzelelo oluphantsi) okanye i-premium-impregnated fibreglass PTFE tape. Imiphezulu ekufutshane ne-PTFE esulungekileyo inikezela ukusebenza okuphezulu kokuchasana nentonga.
2. Ifiber yeglasi / iminerali egcwele izinto eziqinisiweyo
Izinto ezimele: I-Glass fiber iqiniswe i-PA, i-PP, i-PBT, i-calcium carbonate igcwele i-PP. Indlela yokunxiba: Ukunyibilika okuqukuqelayo kufana nephepha lesandpaper elulwelo, ukukrazuka ngokukhawuleza kweengubo eziqhelekileyo zePTFE; i-fiberglass substrate eveziweyo iya kubangela iziphene zokuncamathela. Amanqaku aphambili okukhetha:
1. Ukubaluleka kokutyeba: Khetha iteyiphu yokumelana nomsebenzi onzima we-0.25 mm okanye ngaphezulu.
2. Ukomelezwa kolwakhiwo: Khetha iimveliso ezinomaleko amaninzi we-PTFE okanye unyango oluqina umphezulu endaweni yokwaleka omnye obhityileyo.
3. Iqhinga loTshintsho: Yithathe iteyiphu njengento esetyenziswa rhoqo kwezo meko zokusebenza, kwaye usete imijikelo yokuhlolwa kwamaxesha athile kunye nokutshintshwa endaweni yokusukela ubomi benkonzo esisigxina.
3. Izinto eziphathekayo ezinezongezo ezidliwayo okanye ezimanzi
Izinto ezimele: I-PVC enzima (ikhupha i-HCl), i-flame retardant compounds (i-brominated, i-phosphorus-based flame retardant precipitation), i-fluorinated processing aids. Imodi yokungaphumeleli: I-precipitates igugule i-adhesive layer okanye ingene kwi-substrate, okubangela ukuba i-tape blistering kunye ne-delamination.
1. Ukumelana nemichiza yokuncamathelisa: Qinisekisa ukuba i-adhesive ye-silicone ine-inertness eyaneleyo ngokuchasene ne-acids ebuthakathaka, iiplastiki kunye nezinye i-precipitates.
2. I-substrate exineneyo: Khetha iteyiphu ene-fiberglass elukiweyo ngokuqinileyo kwaye itywinwe ngokupheleleyo ukufakwa kwe-PTFE ukuthintela ukungena kwerhasi/ulwelo olonakalisa isincamathelisi esixhasayo.
3. Ukwandiswa kokuphuma komoya: Dibanisa ukutsalwa kwevacuum yokungunda okanye imijelo eyongezelelweyo yokukhupha umoya ukuba kukho imfuneko yokunciphisa ukuqokelelana kwamanzi kujongano lweteyiphu ukusuka kumthombo.
4. Izinto eziphathekayo ezinobuthathaka
Iimeko eziqhelekileyo: I-electronic component injection molding, high-flow PP ifilimu extrusion. Ukhetho olucetyiswayo: Iteyiphu ye-PTFE ye-Anti-static (itheyiphu ye-PTFE emnyama eqatywe ngekhabhoni eqhubayo emnyama okanye umaleko okhethekileyo ochasene ne-static) ukuphepha ukubhengezwa kothuli kunye neengozi zokukhupha i-electrostatic.
III. Ukulungelelanisa ngokusekwe kwiSixhobo kunye neemeko zeSicelo
1. Isitofu sokubumba ukubumba
Imingxunya, izilayidi kunye neziphakamisi: Iteyiphu idla ngokusetyenziswa kwiindawo zokuncamathelisa umngundo. Iteyiphu ebhityileyo eyi-0.13 mm enokwandiswa okulungileyo iyafuneka ukuze ilingane imiphezulu egobileyo. Ziphephe izikhonkwane ze-ejector kunye neendawo zokungena; sebenzisa isilumkiso kumalungu achanekileyo njengoko ubukhulu beteyiphu buya kutshintsha ukunyamezela kwemveliso. Iipleyiti zembaleki ezishushu kunye neengcebiso zombhobho: Amaqondo obushushu aphezulu kakhulu asebenza apha; kuphela ilaphu le-PTFE elincamathelayo elingagungqiyo ngoomatshini kuphela elinokusetyenziswa ukunqanda ukuncamatheliswa kweflash. I-tape yokuzimela ngokwayo inqatshelwe ngokungqongqo.
2. Extruders kunye nezixhobo ezisezantsi
Imilebe yokuphuma kwe-Extrusion die / outlets: Thintela ukuqokelelwa kwenyibilika kunye neentambo kwindawo yokukhupha. Khetha iteyiphu yokukhutshwa okuphezulu kakhulu (0.08 mm–0.13 mm) ukunqanda ukuguqula imilinganiselo ye-die orifice. Songa iteyiphu ukusuka ngaphambili ukuya ekupheleni kobuso bendawo yokuphuma ukuze unciphise ukungenwa kwenyibilika kumalungu emilenze. Itemplate yePelletizer: Ivezwe ngokuthe ngqo kwiqondo eliphezulu lokunyibilika kunye neglasi yefiber abrasion. Iteyiphu yobunzima obuyi-0.25 mm okanye ngaphezulu inyanzelekile, kwaye ilawulwa njengesiqhelo esisetyenziswayo. Imiqulu yefilimu edlalwayo / i-traction rolls: I-Anti-stick kwaye kulula ukuyicoca. Itheyiphu ye-PTFE exhaswa nge-Silicone inokusongwa kwi-roller, okanye imikhono ye-fiberglass ye-PTFE engancamathiseli ingamkelwa. Qinisekisa ukumelana nobushushu beteyiphu ihambelana nobushushu bomphezulu we-roller ukuba ukufudumeza kubandakanyeka.
