Polyamide (PA) ke polymer e nang le lihlopha tse pheta-phetoang tsa amide ketane e kholo.Hangata e bitsoang Nylon, PA ke e 'ngoe ea lipolasetiki tsa boenjiniere tsa khale tse ntlafalitsoeng le tse sebelisoang haholo.Sehloohong sena kajeno,Qingdao Sainuoe tla u nka hore u tsebe lintlha tse leshome tsa bohlokoa tsa phetoho ea nylon.

pp bokabakeng sa Nylon e fetotsoeng

Thepa e khethehileng ea nylon e etsa hore e sebelisoe haholo likoloing, lisebelisoa tsa elektronike le tsa motlakase, mohaho oa mechine, thepa ea lipapali, masela joalo-joalo.Leha ho le joalo, ka miniaturization ea likoloi, ts'ebetso e phahameng ea lisebelisoa tsa elektroniki le tsa motlakase, le ho potlakisa ts'ebetso ea lisebelisoa tsa mochini tse bobebe, tlhoko ea nylon le ts'ebetso ea eona e ntse e eketseha butle-butle.Kahoo ho fetola nylon ho bohlokoa haholo.
Litaba tse hlokang ho hlokomeloa ha ho fetoloa nylon
1. Ho beha mocheso oa moqomo
(1) Kaha nylon ke polima e kristale, sebaka sa eona sa ho qhibiliha se hlakile.Mocheso oa moqomo oa resin ea nylon ha o etsoa ka ente o amana le thepa ea resin, lisebelisoa le sebopeho sa sehlahisoa.
(2) Mocheso o phahameng haholo oa thepa o bonolo ho baka phetoho ea 'mala, brittleness le terata ea silevera, ha mocheso o tlase haholo oa thepa o etsa hore thepa e be thata' me e ka senya "die and screw".
(3) Ka kakaretso, mocheso o tlase oa ho qhibiliha oa PA6 ke 220 ℃ le PA66 ke 250 ℃.Ka lebaka la botsitso bo futsanehileng ba mocheso oa nylon, ha e tšoanelehe ho lula ka har'a moqomo nako e telele mocheso o phahameng, e le hore e se ke ea etsa hore ho be le mebala le mosehla oa thepa.Ka nako e ts'oanang, ka lebaka la metsi a matle a nylon, e phalla ka potlako ha mocheso o feta sebaka sa eona sa ho qhibiliha.
2. Boemo ba mocheso oa hlobo
(1) Thempereichara ea hlobo e na le tšusumetso e itseng holim'a kristale le ho fokotseha ha hlobo.Mocheso oa hlobo o tloha ho 80 ℃ ho isa ho 120 ℃.Mocheso o phahameng oa hlobo, crystallinity e phahameng, ho hanyetsa ho apara ho eketsehileng, ho thatafala, modulus ea elasticity, ho fokotseha ha metsi, ho fokotseha ha ho bōptjoa, ho loketse lihlahisoa tse teteaneng;
(2) Haeba botenya ba lerako bo feta 3 mm, ho kgothaletswa ho sebelisa hlobo e tlase ea mocheso ka 20 ~ 40 ℃.Bakeng sa lisebelisoa tse matlafalitsoeng ka khalase, mocheso oa hlobo o lokela ho ba holimo ho 80 ℃.

3. Botenya ba lebota la lihlahisoa
Karo-karolelano ea bolelele ba nylon ke 150-200, botenya ba lerako la sehlahisoa ha bo ka tlase ho 0.8mm, ka kakaretso ke 1-3.2mm, 'me ho fokotseha ha sehlahisoa ho amana le botenya ba lerako la sehlahisoa.Ha lerako le le letenya, ho fokotseha ho hoholo hoa kholoanyane.
4. Mokhathala
Boleng bo khaphatsehang ba resin ea nylon bo ka ba 0.03mm, ka hona, groove ea lesoba la exhaust e lokela ho laoloa ka tlase ho 0.025.
5. Semathi le heke
Bophara ba lesoba la heke ha boa lokela ho ba ka tlase ho 0.5T (t ke botenya ba karolo ea polasetiki).Ka heke e ka tlas'a metsi, bophara bo fokolang ba heke e lokela ho ba 0.75mm.
6. Lethathamo la ho tlatsa fiber ea khalase
Ts'ebetsong ea ho bopa nylon, ho fokotsa mocheso oa hlobo, ho eketsa khatello ea ente le ho fokotsa mocheso oa thepa ho tla fokotsa ho fokotseha ha nylon ho isa tekanyong e itseng, ho eketsa khatello ea ka hare ea sehlahisoa le ho etsa hore ho be bonolo ho holofala.Ka mohlala, ho fokotseha ha PA66 ke 1.5% ~ 2%, ho fokotseha ha PA6 ke 1% ～ 1.5%, 'me ho fokotseha ho ka fokotsoa hoo e ka bang 0.3% ka mor'a ho eketsa motsoako oa fiber fiber.
Boiphihlelo bo sebetsang bo re bolella hore ha fiber ea khalase e eketsoa haholoanyane, ho honyela ha lesela la nylon ho fokotseha.Leha ho le joalo, haeba fiber ea khalase e eketsoa haholo, e tla baka fiber e phaphametseng ka holim'a metsi, ho se lumellane le liphello tse ling.Ka kakaretso, phello ea ho eketsa 30% e batla e le ntle.
7. Tšebeliso ea thepa e sebelisoang hape
Ho molemo hore u se ke ua feta ka makhetlo a mararo ho qoba ho fetoha ha sehlahisoa kapa ho theoha ho hoholo ha thepa ea 'mele le ea mechine.Chelete ea kopo e lokela ho laoloa ka tlase ho 25%, e ngata haholo e tla baka ho fetoha ha maemo a ts'ebetso, 'me motsoako oa lisebelisoa tse nchafalitsoeng le lisebelisoa tse ncha li tlameha ho omisoa.
8. Litaelo tsa polokeho
Ha resin ea nylon e qala, mocheso oa molomo o lokela ho buloa pele, ebe mocheso o lokela ho futhumatsoa ka har'a moqomo oa ho fepa.Ha nozzle e thibiloe, u se ke ua tobana le lesoba la spray, e le ho thibela ho lokolloa ha tšohanyetso ha moqomo oa ho fepa ka lebaka la ho bokella khatello, e ka bakang kotsi.

9. Kopo ea moemeli oa tokollo
Tšebeliso ea karolo e nyane ea moemeli oa ho lokolla hlobo ka linako tse ling e ka ntlafatsa le ho felisa bubble le liphoso tse ling.Sehlahisoa sa ho lokolloa ha lihlahisoa tsa nylon e ka ba zinc stearate le oli e tšoeu, kapa e kopantsoe le peista.Palo ea moemeli oa tokollo e tlameha ho ba e nyane le e ts'oanang ho qoba liphoso tse kaholimo.Sekurufu se lokela ho ntšoa ha mochini o koetsoe ho thibela screw ho robeha nakong ea tlhahiso e latelang.

10. Kalafo ea poso
(1) Lihlahisoa li lokela ho phekoloa ka mocheso ka mor'a ho thehoa
Mekhoa e tloaelehileng ea oli ea diminerale, glycerin, parafine ea metsi le metsi a mang a phahameng a belang, mocheso oa mocheso oa mocheso o lokela ho ba 10 ~ 20 ℃ ho feta mocheso oa tšebeliso, 'me nako ea phekolo e itšetlehile ka botenya ba lerako la sehlahisoa.Botenya bo ka tlase ho 3 mm ke 10 ~ 15 min, botenya ke 3 ~ 6 mm, 'me nako ke 15 ~ 30 min.sehlahisoa ka mor'a ho phekoloa ha mocheso se lokela ho pholile butle-butle ho mocheso oa kamore, e le ho thibela ho pholile ka tšohanyetso ho baka ho hlahisa khatello ea maikutlo ho sehlahisoa.
(2) Lihlahisoa li lokela ho tšoaroa ka taolo ea mongobo ka mor'a ho bōptjoa
Taolo ea mongobo e sebelisoa haholo-holo bakeng sa lihlahisoa tse nang le mongobo o phahameng.Ho na le mekhoa e 'meli: o mong ke ho belisa mongobo oa metsi;E 'ngoe ke mokhoa o metsi oa tharollo ea metsi a potassium acetate (karolelano ea potassium acetate ho metsi ke 1.25: 1, ntlha e belang 121 ℃).
Metsi a belang a bonolo, hafeela sehlahisoa se behiloe tikolohong ea mongobo oa 65%, e le hore se ka finyella ho kenngoa ha mongobo o lekanang, empa nako e telele.Mocheso oa phekolo oa potassium acetate aqueous solution ke 80 ~ 100 ℃, 'me nako ea phekolo haholo-holo e itšetlehile ka botenya ba lerako la sehlahisoa, ha botenya ba lerako ke 1.5mm, hoo e ka bang 2h, 3mm, 8h, 6mm, 16 ~ 18h.
