Farsamaynta polarization Electrostatic
Maaddada loo isticmaalo shaandhada hawada electret waxay u baahan tahay sifooyin dielectric heer sare ah, sida iska caabbinta jidhka oo sarreeya iyo caabbinta dusha sare, xoogga burburka dielectric sare, nuugista qoyaanka hooseeya, iyo xajinta hawada.
Maaddada noocaan ah waxay inta badan ka kooban tahay alaabada polar organic sare ee polymer, sida alaabta aan dabaylaha ahayn sida polypropylene, polytetrafluoroethylene, hexafluoropropylene/tetrafluoroethylene copolymers, iwm; Maaddooyinka cirifka ah ama kuwa daciifka ah: Polytrifluoroethylene, polypropylene (isku dhafan), polyester, iwm.
Xabagta dhalaalaysa ee sare ee polypropylene waxa ay noqotay wax la door bidayo in ay dhalaaliso tignoolajiyada korantada ee la afuufay taas oo ay ugu wacan tahay wax qabadkeeda habaysan ee aad u wanaagsan, qiimo jaban, iyo polarizability wanaagsan. Si kastaba ha noqotee, ficil ahaan, awoodeeda haynta elektrostatic waxaa si weyn u saameeya arrimo ay ka mid yihiin heerkulka, qoyaanka, iyo wakhtiga kaydinta, taasoo keentay waxtarka sifaynta aan degganayn.
Si loo fahmo isbeddelada qadarka dallacaadda, xawaaraha dallacaadda, dallaca xasilloonida ee xaaladaha kala duwan, hufnaanta sifaynta, iyo dhibicda danab ee eedeymaha taagan dusha sare ee dharka dhalaalaysa, cilmi-baarayaasha gudaha iyo dibadda ayaa sameeyay cilmi-baaris ballaaran oo ku saabsan habka polarization iyo polarization Masterbatch technology.
Fluorine waa curiyaha leh electronegativity ugu sarreeya wuxuuna leeyahay awoodda ugu weyn ee "helida elektarooniga". Electron-yada ay qabteen atamka fluorine si sahal ah uma baxsan karaan waxayna si wax ku ool ah u wanaajin karaan waxqabadka sifaynta iyo nolosha adeegga agabka shaandhada.
Iyada oo la kaashanayo teknoolajiyada kala duwan ee elektrostatic balasmaha sida AC corona ama DC corona, atomyada fluorine ee qayb ahaan buuxa ayaa ionized, iyo xaaladaha farsamada qaarkood, qaybaha fluorine-kan ayaa xitaa qayb ahaan isku dari kara fiilooyinka polypropylene si ay u sameeyaan waxa loo yaqaan agabka "hybrid" ee goobta cilmi baarista.
Machadyada gudaha sida Jaamacadda Donghua waxay sameeyeen cilmi-baaris qoto-dheer oo ku saabsan waxqabadka sifeynta ee walxahan isku-dhafka ah ee ku jira dharka dhalaalka ah ee polypropylene.
Ultra fine Organic Fluorine Electret budada TF11
Budada polarizing fluorine ee aadka u fiican ee TF11 waxay leedahay awood koronto oo aad u saraysa, waxayna si wayn u wanaajin kartaa hufnaanta sifaynta iyada oo ku daraysa 0.05-0.2% oo kaliya dhar dhalaalaysa. Waxaa inta badan loo isticmaalaa soo saarista dhar dhalaalaysa oo leh hufnaanta shaandhaynta ee 95 ama 99.
Marka la barbardhigo walxaha kale ee budada ah ee aan noolaha ahayn, budada fluorine organic ultrafine lafteedu waxay leedahay sifnaan iyo la jaanqaad wanaagsan oo ay la socoto xabagta polypropylene, taas oo ka dhigaysa mid fudud in la soo saaro masterbatch polar oo ay yar tahay inay xirto spinneret.
Tianshi TF11 budada dabaysha ee fluorine organic waa mid aad u fiican waxayna leedahay meel dhalaalaysa oo sare, taas oo loo arki karo buuxinta inta lagu jiro habka buufinta dhalaalka. Si ka duwan qaar ka mid ah qalabka fluorine-ku ku jiro ee lagu sheegay suugaanta, TF11 lafteedu ma aha fibrose, iyo wax yar oo dheeraad ah oo lagu daro ayaa la filayaa inaanay saameyn ku yeelan tayada fiilooyinka dhalaalay.
Isku-dhafka Tianshi TF11 iyo Molten Finger 1500 PP ayaa loo isticmaalay si loo helo masterbatch polar. Qadarka TF11 ee lagu daray masterbatch polar waa 5-10%, xaalada dheeraadka ah waxay sidoo kale si dhow ula xiriirtaa shuruudaha habka gaarka ah ee qalabka. Mabda 'ahaan, heerkulka extrusion wax yar ka hooseeya ayaa fududayn doona.
Marka lagu qaso budada PP, 5-15% ee Tianshi TF11 budada polar fluorine organic si toos ah ayaa loogu dari karaa inta lagu guda jiro wax soo saarka index dhalaalka 1500 PP si toos ah u soo saaro masterbatch polar.
Masterbatch-ka polar-ka ee la soo saaro sida waafaqsan habka kor ku xusan waxaa lagu daraa 1-3% ee caanaha dhalaalka ah ee la afuufay, ama waxa ku jira Tianshi TF11 waxaa loo xisaabiyaa inay noqdaan agagaarka 0.1-0.2%.
Macaamiisha qaar ayaa sidoo kale isku dayay inay ku daraan 0.2% Tianshi TF11 budada polar organic fluorine budada PP iyada oo loo marayo masterbatch hore isku qasan iyo habab kale si ay u soo saaraan barta dhalaalaysa sare dhalaalaysa walxo afuufay oo leh qalab dabaysha ku dhisan.
Waa maxay faa'iidada saamileyda ah ee Dongguan Liansheng Non Woven Technology Co., Ltd.waxa la aasaasay bishii Maajo 2020 Waxay soo saari kartaa midabyo kala duwan oo ah PP spunbond dhar aan tol lahayn oo ballac ah oo ka yar 3.2 mitir laga bilaabo 9 garaam ilaa 300 garaam.
