Ilaphu elinokuphefumla elibhetyebhetye spunbond pp nonwoven

Iimpawu ze-spunbond pp ngelaphu elingaphothiweyo

1. Ilaphu le-PP le-spunbond elingalukwanga lineempawu zokunganyangeki kwamanzi, ukuphefumla, ukuguquguquka, ukungatsha, okungeyotyhefu kunye nokungacaphukiyo, kunye nemibala ecebileyo. Ukuba izinto zibekwe ngaphandle kwaye ziboliswe ngokwemvelo, ubude bayo obuninzi buyientsuku ezingama-90 kuphela. Ukuba ifakwe ngaphakathi endlwini kwaye ibolile kwiminyaka emi-5, ayinayo ityhefu, ayinavumba, kwaye ayinazinto ezishiyekileyo xa itshisiwe, ngoko ayingcolisi indalo. Ngoko ke, ukukhuselwa kwendalo kuvela kule nto.

2. Ilaphu le-PP elingalukwanga lineempawu zokuhamba kwenkqubo emfutshane, isantya sokuvelisa ngokukhawuleza, isivuno esikhulu, ixabiso eliphantsi, ukusetyenziswa okubanzi, kunye nemithombo yezinto ezininzi ezikrwada.

Uphuhliso lwelaphu leSpunbond pp nonwoven

Ishishini lelaphu le-PP elingalukwanga e-China liphuhlise ngokukhawuleza, lifumana ukukhula ngokukhawuleza kwimveliso kunye nokuthengisa, kodwa kuye kwakho iingxaki ezithile ngexesha lenkqubo yophuhliso. Izizathu zeengxaki ezinje ngesantya esisezantsi soomatshini kunye nenkqubo ecothayo yokwenziwa kwemizi-mveliso inamacala amaninzi. Ukongeza kwizinto ezifana nenkqubo yolawulo kunye nokuthengisa, amandla obugcisa abuthathaka kunye nokungabikho kophando olusisiseko yimiqobo ephambili. Nangona amanye amava emveliso eqokelelwe kwiminyaka yakutshanje, ayikacaciswa kwaye kunzima ukukhokela imveliso yomatshini.

Yintoni uzinzo lwekhemikhali yelaphu le-spunbond pp nonwoven

1. Ukusebenza ngokomzimba

Ilaphu le-PP elingalukwanga le-spunbond alinatyhefu nelingenavumba elimhlophe eliyikristale lepolymer ephezulu, ekungokunje yenye yezona ntlobo zikhaphukhaphu zeeplastiki. Izinzile ngakumbi emanzini kwaye inezinga lokufunxa amanzi eliyi-0.01% kuphela emva kweeyure ezili-14 emanzini. Ubunzima be-molecular buvela malunga ne-80000 ukuya kwi-150000, kunye nokubumba okulungileyo. Nangona kunjalo, ngenxa yezinga eliphezulu lokunciphisa, iimveliso zodonga lwangaphambili zixhomekeke kwi-indentation, kwaye umbala ongaphezulu weemveliso ulungile, okwenza kube lula ukufaka umbala.

2. Iimpawu zoomatshini

Ilaphu leSpunbond pp linokucoceka okuphezulu, ulwakhiwo oluqhelekileyo, kwaye ngenxa yoko lineempawu ezibalaseleyo zoomatshini. Amandla ayo, ukuqina, kunye nokunwebeka kuphezulu kune-PE ephezulu. Olona phawu lubalaseleyo kukuxhathisa ngamandla ukugoba ukudinwa, kunye ne-coefficient eyomileyo ye-friction efana nenayiloni, kodwa ayilunganga njengenayiloni phantsi kwe-oyile yokuthambisa.

3. Ukusebenza kwe-thermal

Ilaphu leSpunbond pp elingalukwanga linokuxhathisa ubushushu obuhle, linendawo yokunyibilika eyi-164-170 ℃. Imveliso inokubulawa iintsholongwane kwaye ivalwe kubushushu obungaphezulu kwe-100 ℃. Ngaphantsi kwamandla angaphandle, ayikhubazeki nakwi-150 ℃. Iqondo lobushushu embrittlement -35 ℃, kwaye embrittlement kwenzeka ngaphantsi -35 ℃, kunye nokumelana nobushushu ngaphantsi PE.

4. Ukusebenza kombane

Ilaphu le-Spunbond pp elingalukwanga linomsebenzi ogqwesileyo wokugquma okuphezulu. Ngenxa yokuba phantse akukho manzi, ukusebenza kwayo kwe-insulation akuchaphazeli ukufuma, kwaye ine-coefficient ephezulu ye-dielectric. Ngokunyuka kwamaqondo obushushu, ingasetyenziselwa ukwenza iimveliso zokugquma umbane ezishushu. I-voltage yokutshatyalaliswa nayo iphezulu kakhulu, iyenza ifaneleke kwizinto zombane, njl njl. Ukumelana nombane ochanekileyo kunye nokumelana ne-arc, kodwa umbane ophezulu we-static kunye nokuguga okulula xa udibana nobhedu.

5. Ukumelana nemozulu

Ilaphu le-Spunbond pp elingalukwanga libuthathaka kakhulu kwimitha ye-ultraviolet. Ukongeza i-zinc oxide thiopropionate lauric acid ester kunye nekhabhoni emnyama efana nezigcwali ezimhlophe zobisi kunokuphucula ukumelana nokuguga.
