Guhumeka byoroshye spunbond pp idoda

Ibiranga spunbond pp idoda

1. PP spunbond idoda idoze ifite ibiranga kurwanya amazi, guhumeka, guhinduka, kudakongoka, kutagira uburozi no kudatera uburakari, namabara meza. Niba ibikoresho bishyizwe hanze kandi mubisanzwe byangirika, igihe kinini cyo kubaho ni iminsi 90 gusa. Niba ishyizwe mu nzu ikangirika mu myaka 5, ntabwo ari uburozi, nta mpumuro nziza, kandi nta bintu bisigara iyo bitwitswe, bityo ntibihumanya ibidukikije. Kubwibyo, kurengera ibidukikije biva muribi.

2. PP idoda idoda ifite ibiranga inzira ngufi, umuvuduko mwinshi, umusaruro mwinshi, igiciro gito, gukoresha cyane, hamwe nibikoresho byinshi bibisi.

Iterambere rya Spunbond pp idoda

Inganda za PP zidoda mu Bushinwa zateye imbere byihuse, zigera ku iterambere ryihuse mu bicuruzwa no kugurisha, ariko kandi hari ibibazo byagaragaye mugihe cyiterambere. Impamvu zibibazo nkigipimo gito cya mashini hamwe ninganda zitinda zinganda ni nyinshi. Usibye ibintu nka sisitemu yo gucunga no kwamamaza, imbaraga za tekinike nke no kubura ubushakashatsi bwibanze nimbogamizi nyamukuru. Nubwo ubunararibonye bwibikorwa byakusanyirijwe mumyaka yashize, ntiburashyirwa mubikorwa kandi biragoye kuyobora umusaruro wimashini.

Ni ubuhe buryo bukomeye bwimiti ya spunbond pp idoda

1. Imikorere yumubiri

PP imyenda idoda idoda ni uburozi kandi butagira impumuro y'amata yera yera ya kristaline polymer, kuri ubu ni bumwe mu bwoko bworoshye bwa plastiki. Irahagaze neza cyane kumazi kandi ifite igipimo cyo kwinjiza amazi 0,01% gusa nyuma yamasaha 14 mumazi. Uburemere bwa molekile buri hagati ya 80000 na 150000, hamwe nuburyo bwiza. Nyamara, bitewe nigipimo kinini cyo kugabanuka, ibicuruzwa byurukuta rwumwimerere bikunda kwerekanwa, kandi ibara ryubuso bwibicuruzwa nibyiza, bigatuma byoroshye kurangi.

2. Ibikoresho bya mashini

Spunbond pp idoda idoze ifite isuku ihanitse, imiterere isanzwe, niyo mpamvu ifite imiterere yubukanishi. Imbaraga zayo, ubukana, hamwe na elastique birenze hejuru yubucucike bukabije PE. Ikintu kigaragara ni ukurwanya gukomeye kunaniza umunaniro, hamwe na coeffisente yumye yumye isa na nylon, ariko ntabwo ari nziza nka nylon munsi yo gusiga amavuta.

3. Imikorere yubushyuhe

Spunbond pp idoda idoze ifite ubushyuhe bwiza, hamwe no gushonga ya 164-170 ℃. Ibicuruzwa birashobora kwanduzwa no guhindurwa mubushyuhe buri hejuru ya 100 ℃. Nta mbaraga zo hanze, ntabwo zihinduka no kuri 150 ℃. Ubushyuhe bwo gutwika ni -35 ℃, kandi kwinjiza bibaho munsi ya -35 ℃, hamwe nubushyuhe buke ugereranije na PE.

4. Imikorere y'amashanyarazi

Spunbond pp idoda idoze ifite imikorere myiza yumurongo mwinshi. Bitewe nuko hafi ya yose itinjira mu mazi, imikorere yayo ntishobora gukoreshwa nubushuhe, kandi ifite coefficente ya dielectric. Hamwe n'ubwiyongere bw'ubushyuhe, burashobora gukoreshwa mugukora amashanyarazi ashyushye. Umuvuduko wo kumeneka nawo ni mwinshi cyane, bigatuma ubera ibikoresho byamashanyarazi, nibindi. Kurwanya voltage nziza hamwe no kurwanya arc, ariko amashanyarazi ahamye hamwe no gusaza byoroshye mugihe uhuye numuringa.

5. Kurwanya ikirere

Spunbond pp imyenda idahwitse yunvikana cyane kumirasire ya ultraviolet. Ongeramo zinc oxyde thiopropionate lauric acide ester na karubone umukara nkamata yera yuzuye birashobora kunoza gusaza.
