Zeziphi iintlobo zeentsinga ezidla ngokusetyenziswa kudaka lwepolymer?

Ukongeza iintsinga kudaka lwepolymer ukuphucula ukusebenza okubanzi kodaka kuye kwaba yindlela eqhelekileyo nenokwenzeka.Iintsinga ezisetyenziswa ngokuqhelekileyo zezi zilandelayo

I-fiberglass ekwaziyo ukumelana nealkali?

Ifayibha yeglasi yenziwa ngokunyibilika kwesilicon dioxide, iioksidi ezinealuminiyam, icalcium, iboron kunye nezinye izinto, kunye nenani elincinci lezinto zokuncedisa ekusetyenzweni ezifana nesodium oxide kunye nepotassium oxide kwiibhola zeglasi, emva koko zinyibilike kwaye zizoba iibhola zeglasi kwicrucible.Umsonto ngamnye otsalwe kwi-crucible ubizwa ngokuba yi-monofilament, kwaye zonke i-monofilaments ezithathwe kwi-crucible zihlanganiswe zibe yintambo eluhlaza (i-tow) emva kokudlula kwi-tank yokucwina.Emva kokuba i-tow isikiwe, ingasetyenziswa kwi-polymer mortar.

Iimpawu zokusebenza zefiber yeglasi zinamandla aphezulu, imodyuli ephantsi, ubude obuphezulu, i-coefficient yolwandiso olusezantsi, kunye ne-thermal conductivity ephantsi.Amandla e-tensile yefiber yeglasi idlula kakhulu amandla ezinto ezahlukeneyo zentsimbi (1010-1815 MPa).

Ifayibha yeVelen?

Icandelo eliphambili le-vinylon yi-polyvinyl alcohol, kodwa i-vinyl alcohol ayizinzile.Ngokuqhelekileyo, i-vinyl alcohol acetate (vinyl acetate) enentsebenzo ezinzileyo isetyenziswa njenge-monomer ukwenza i-polymerize, kwaye emva koko i-acetate ye-polyvinyl ephumayo i-alcohollated ukufumana i-polyvinyl alcohol.Emva kokuba i-silika iphathwe nge-formaldehyde, i-vinylon ekwazi ukumelana namanzi ashushu inokufumaneka.Iqondo lobushushu lokunyibilika (225-230C) lwepolyvinyl yotywala buphezulu kunobushushu bokubola (200-220C), ngoko ke busonjululwa ngesisombululo.

IVinylon ine-hygroscopicity eyomeleleyo kwaye lolona didi lwehygroscopic phakathi kwemicu yokwenziwa, ekufutshane nomqhaphu (8%).IVinylon yomelele kancinci kunomqhaphu kwaye yomelele kakhulu kunoboya.Ukumelana ne-Corrosion kunye nokumelana nokukhanya: i-insoluble ngokubanzi kwi-asidi ye-organic, i-alcohols, i-esters kunye ne-solvents yesibane se-petroleum, akukho lula ukubumba, kwaye ilahleko yamandla ayikho enkulu xa ibonakaliswe ilanga.Ukungalungi kukuba ukuxhathisa kwamanzi ashushu akulunganga ngokwaneleyo kwaye i-elasticity ihlwempuzekile.

Ifayibha yeAkriliki?

Ibhekisela kwi-fiber yokwenziwa eyenziwe ngokujikeleza okumanzi okanye ukujikeleza okomileyo ngaphezu kwe-85% ye-copolymer ye-acrylonitrile kunye ne-monomers yesibini neyesithathu.

Ifayibha ye-Acrylic inokumelana nokukhanya okugqwesileyo kunye nokumelana nemozulu, eyona ilungileyo phakathi kwemicu ye-textile eqhelekileyo.Xa i-acrylic fiber ibonakaliswe elangeni unyaka omnye, amandla ayo aya kuncipha kuphela ngama-20%.Ifayibha ye-Acrylic inozinzo oluhle lweekhemikhali, ukuxhathisa kwe-asidi, ukuxhathisa okubuthathaka kwe-alkali, ukuxhathisa i-oxidation kunye nokumelana ne-solvent ye-organic.Nangona kunjalo, iifayili ze-acrylic ziya kujika ziphuzi kwi-lye, kwaye i-macromolecules iya kuphuka.I-quasi-crystalline structure ye-acrylic fiber yenza i-fiber thermoelastic.Ukongeza, ifayibha ye-acrylic inokumelana nobushushu obulungileyo, akukho mkungu, kwaye ayoyiki izinambuzane, kodwa inokumelana nokunxiba kakubi kunye nozinzo olubi lwe-dimensional.

Iintsinga zePolypropylene?

Ifayibha yepolyolefin eyenziwe nge-stereoregular isotactic polypropylene polymer ngokunyibilika ukusonteka.Uxinaniso olunxulumeneyo lolona luncinci phakathi kweentsinga zokwenziwa, ukomelela kunye nokomelela okumanzi kuyalingana, kwaye ukuxhathisa ukubola kweekhemikhali kulungile.Kodwa ilanga ukuguga lihlwempu.Xa i-polypropylene mesh fiber ifakwe eludongeni, ngexesha lokuxuba udaka, uxhulumaniso olunqamlekileyo phakathi kwe-fiber monofilaments lutshatyalaliswa ngokuxutywa kunye nokukhuhlana kodaka ngokwalo, kwaye i-fiber monofilament okanye isakhiwo sothungelwano sivulwa ngokupheleleyo, ngoko. ukuze kuqondwe ubuninzi Isiphumo seentsinga ezininzi zepolypropylene ezixutywe ngokulinganayo kwikhonkrithi.

Ifibre yenayiloni?

I-Polyamide, eyaziwa ngokuba yi-nylon, ligama eliqhelekileyo le-resins ye-thermoplastic equkethe amaqela e-amide aphindaphindiweyo-[NHCO]-kwi-chain chain ye-molecular.

Inayiloni inamandla omatshini aphezulu, indawo yokuthambisa ephezulu, ukumelana nobushushu, ukungqubana okuphantsi, ukumelana nokunxiba, ukuzithambisa, ukufunxa ukothuka kunye nokunciphisa ingxolo, ukumelana ne-oyile, ukuxhathisa okubuthathaka kwe-asidi, ukuxhathisa kwealkali kunye nezinyibilikisi ngokubanzi, ukugqunywa kombane okulungileyo, kunokuzenzela ukucima, akukho tyhefu, ivumba, ukumelana kakuhle nemozulu, ukudaya kakubi.Ukungalungi kukuba inokufakwa kwamanzi aphezulu, okuchaphazela ukuzinza kwe-dimensional kunye neempawu zombane.Ukuqiniswa kweFiber kunokunciphisa ukufunxa kwamanzi kwi-resin, ukwenzela ukuba isebenze phantsi kobushushu obuphezulu kunye nomswakama ophezulu.Inayiloni inobudlelwane obuhle kakhulu kunye nemicu yeglasi.

Polyethylene fiber?

Iintsinga zePolyolefin zisontelwe kwi-polyethylene yomgama (i-polyethylene yoxinaniso oluphezulu) ngokunyibilika ngokusonta.Iimpawu zesixhobo zezi:

(1) Amandla eFayibha kunye nobude busondele kwezo zepolypropylene;

(2) Umthamo wokufunxa ukufuma uyafana nowe-polypropylene, kwaye izinga lokufuma kwakhona kokufuma nguziro phantsi kweemeko eziqhelekileyo zomoya;

(3) Ineempawu zeekhemikhali ezizinzileyo, ukuxhathisa okuhle kweekhemikhali kunye nokuxhathisa ukubola;

(4) Ukumelana nobushushu kubi, kodwa ukuxhathisa ubushushu kunye nokufuma kungcono, indawo yayo yokunyibilika i-110-120 ° C, ephantsi kunezinye iifayili, kwaye ukuxhathisa kwimingxuma yokunyibilika kubi kakhulu;

(5) Inokufakwa kakuhle kombane.Ukumelana nokukhanya kubi, kwaye kulula ukuguga phantsi kokukhanya kokukhanya.

Ifayibha yeAramid?

Ikhonkco eliphambili le-polymer macromolecule yenziwe ngamakhonkco amnandi kunye neebhondi ze-amide, kwaye ubuncinane i-85% yamaqela e-amide adibaniswe ngokuthe ngqo kwiindandatho ezimnandi;iiathom zenitrogen kunye namaqela e-carbonyl kumaqela e-amide yeyunithi nganye ephinda-phindayo idityaniswe ngokuthe ngqo kumakhonkco anevumba elimnandi. imicu ye-aramid.

Ifayibha ye-Aramid ineepropathi ezigqwesileyo zoomatshini kunye neziguquguqukayo ezinje ngokuqina kokuqina okuphezulu, imodyuli ephezulu yokuqina, ukuxinana okuphantsi, ukufunxa kakuhle kwamandla kunye nokufunxa ukothuka, ukuxhathisa ukunxiba, ukumelana nempembelelo, ukumelana nokudinwa, kunye nokuzinza komda.I-Chemical corrosion, ukumelana nobushushu obuphezulu, ukwanda okuphantsi, i-conductivity ephantsi ye-thermal, engatshiyo, enganyibilikiyo kunye nezinye iimpawu ezibalaseleyo zokushisa kunye neempawu ezibalaseleyo ze-dielectric.

Umcu womthi?

Umcu womthi ubhekisa kwithishu esebenza ngomatshini eyenziwe ludonga lweseli olungqingqwa kunye neeseli zefayibha ezinemingxuma ecolekileyo efana nokuqhekeka, kwaye yenye yezona zinto ziphambili zexylem.

I-Wood fiber yintsinga yendalo efunxa amanzi kwaye ayinyibiliki emanzini.Inokuguquguquka okugqwesileyo kunye nokusasazeka.
