1.Izincazelo ze-aramid fibers
I-ARAMID fiber yigama elihlangene lemicu ye-polyamide ye-aromatic polyamide.
I-2.Classified of Aramid Fibers
I-ARAMID fiber ngokokwakheka kwamangqamuzana ingahlukaniswa ngezinhlobo ezintathu: i-polyamide fiber ye-polyamide, i-polyamide fiber, i-poly-polyamide copolymer fiber. Phakathi kwazo, imicu ye-polyamide ye-para-aromatic ihlukaniswe yaba yi-poly-phenylamide) imicu, imicu ye-poly-benzisicarboxboxbox7 I-Poly-n, NM-TOLYL-BIS- (Isobenzamide) Fibers terephthalamide.
3.Imifanekiso ye-ARAMID Fibers
1. Izakhiwo ezinhle zemishini
I-Interposition i-polymer eguqukayo, ibhidliza amandla aphezulu kune-polyester ejwayelekile, ukotini, i-nylon, njll.
2. Ilangabi elihle kakhulu nokumelana nokushisa
I-Oxygen Index ye-Oxygen (Loi) ye-M-ARAMID iyi-28, ngakho-ke ayiqhubeki ukushisa lapho ishiya ilangabi. Izakhiwo ze-Flame Retardant ze-M-ARAMID zinqunywa ngesakhiwo sazo samakhemikhali, okwenza kube yifayibha elivuthayo laphakade elingapheli amandla noma alahlekelwe yimithombo yalo yokubuyisa amalangabi ngokuhamba kwesikhathi noma ukugeza. I-M-ARAMID iyazinza kahle futhi ingasetshenziswa ngokuqhubekayo ku-205 ° C futhi igcina amandla aphezulu emazingeni okushisa amakhulu kune-205 ° C. I-M-ARAMID inokushisa okuphezulu kokuwohloka futhi ayincibiliki noma idonsa emazingeni okushisa aphezulu, kepha iqala kuphela ukubhebhana emazingeni okushisa amakhulu kune-370 ° C.
3. Izakhiwo zamakhemikhali ezinzile
Ngaphezu kwama-acid aqinile nezisekelo, ama-ARAMID acishe athintwa yi-solvents ye-organic kanye namafutha. Amandla amanzi e-ARAMID acishe alingana namandla owomile. Ukuqina komugqa wamanzi agcwele kungcono kunalokho kweminye imicu ye-organic.
I-ARAMID iyazwela kakhulu ukukhanya kwe-UV. Uma kuvezwa ilanga isikhathi eside, lilahlekelwa amandla amaningi futhi ngakho-ke kufanele livikelwe ngongqimba oluvikelayo. Le nhlangano evikelayo kufanele ikwazi ukuvimba ukulimala kumathambo a-ARAMID kusuka ku-UV.
4. Ukumelana nemisebe
Ukuphikiswa kwemisebe yama-aramid ahle kakhulu. Isibonelo, ngaphansi kwe-1.72x108rad / S ye-R-radiation, amandla ahlala njalo.
5. Ukuqina
Ngemuva kokugeza okungu-100, amandla ezindwangu ze-m-aramid asengafinyelela ngaphezu kwama-85% amandla abo okuqala. Ukumelana nezinga lokushisa kwama-para-aramid kuphakeme kunalokho kwama-aramid ahlukahlukene, ngokuqhubeka okujwayelekile kokushisa okungu-104 ° C kuya ku-204 ° C futhi akukho okubolile noma ukuncibilikisa ngo-560 ° C. Isimo esibaluleke kakhulu se-para-aramid ngamandla aso aphezulu kanye namamodulomu aphezulu, amandla ayo angaphezu kuka-25g / Dan izikhathi ezi-5 I-modulus yayo izikhathi ezi-2 ~ 3 zensimbi esezingeni eliphakeme noma ngefayibha yengilazi kanye nezikhathi eziyi-10 zamandla aphezulu we-Nylon Indambo Yezimboni. Ukwakheka okungafani kobuso be-aramid pulp, etholakala nge-fibrillation engaphezulu kwemicu yama-aramid, kuthuthukisa kakhulu ukubamba kwe-compound futhi ngakho-ke ihle kakhulu njengefayibha eliqinisiwe lemikhiqizo evuthayo. I-ARAMID pulp hexagonal special fiber i aramid 1414 pulp, i-flocculent ephuzi, i-plush, ukuqina okuphezulu, ukuqina okuphezulu, ukuqina okuhle, ukuqina okuhle, ubude obukhulu bokuqina, ubude obukhulu bokuqina, ubude obukhulu bokuqina, ubude obukhulu bokulimala okungu-2-2.5mm nangaphezulu indawo ka-8m2 / g. Isetshenziswa njengezinto zokuqinisa ze-gasket ngokuqina okuhle nokusebenza uphawu, futhi akunangozi empilweni yabantu kanye nemvelo, futhi kungasetshenziselwa ukubopha uphawu emanzini, uwoyela, futhi kungasetshenziswa ama-acid acid kanye ne-alkali. Kufakazelwe ukuthi amandla omkhiqizo alingana nama-50-60% emikhiqizo eqinisiwe ye-asbestos lapho kufakwa ngaphansi kwe-10% ye-slurry. Isetshenziselwa ukuqinisa izinto ezingqubuzanayo nezindawo zokubopha kanye neminye imikhiqizo eyenziwe, futhi ingasetshenziswa njengenye indlela ye-asbestos yezinto zokwakha uphawu lokuphambanisa, iphepha eliphakeme lokuvimbela ukumelana nokuqina kokuvimbela iphepha lokuvimbela kanye nezinto zokuqinisekiswa kokuvilapha okuqinisiwe.
