Izinto zepolyester ezingalukwanga

Ilaphu lePolyester spunbond elingalukwanga linamandla aphezulu, ukumelana nobushushu obuphezulu (inokusetyenziswa ixesha elide kwindawo eyi-150 ℃), ukumelana nokwaluphala, ukumelana ne-UV, ubude obuphezulu, ukuzinza okuhle kunye nokuphefumla, ukumelana nomhlwa, ukugqunywa kwesandi, ukuxhathisa inundu, kunye nokungabi natyhefu.

Iimpawu zezinto ezibonakalayo

1. Iintsinga zepolyester zinokumelana okugqwesileyo kokushwabana, ukunwebeka, kunye nokuzinza kwe-dimensional, kunye neempawu ezilungileyo zokugquma umbane. Ziyakwazi ukumelana nokukhanya kwelanga, ukukhuhlana, ukungunda nokubola. Kwakhona banokuchasana kakuhle kwi-reagents yeekhemikhali kwaye banokumelana ne-acids ebuthakathaka kunye ne-alkalis.

2. Kwiqondo lokushisa lokushisa, unamandla athile okumelana ne-dilute kunye ne-acids eqinile, kodwa ukuchasana kakubi kwi-alkalinity enamandla.

3. Ukusebenza kokudaya kwee-polyester fibers kubi, kwaye ngokubanzi kufuneka kudayiwe ngeedayi ezihlakaziweyo kumaqondo obushushu aphezulu okanye phambi kwabathwali.

Ukusetyenziswa kwelaphu lepolyester elingalukwanga

1. Isetyenziselwa ukuhlobisa kwangaphakathi, ilaphu lesiseko sekhaphethi, ilaphu leshishini lamayeza, i-fluff, i-lining, njl.

2. Isetyenziselwa ukwakhiwa, ukukhutshwa kwamanzi ophahleni kusebenza njengendwangu yesiseko, kunye nesanti, i-samente, njl njl.

3. Isetyenziswe ekwakhiweni, ngumlinganiselo othathwayo ukukhusela iintanda.

4. Ngokweempawu zokuguga kunye nokumelana nobushushu obuphezulu beempahla ze-spunbond ezingalukwanga, zisetyenziswa ngokubanzi kwiingubo zasekhaya, izinto ezidibeneyo, izinto zemithwalo, njl. Kwaye ngenxa yokungagugi; Yaziwa kakhulu ngabathengi.

Imarike yepolyester spunbond ilaphu elingalukwanga

Ukusetyenziswa kwe-geotextiles kumazwe angaphandle kwaqala kwangeminyaka yoo-1960. I-United States lelona lizwe lisebenzise kakhulu i-geotextiles emhlabeni. Ekuqaleni kweminyaka yee-1990, ukusetyenziswa kwayo ngonyaka kwakungaphezu kwe-300 yezigidi zesikwemitha, kwaye kwiminyaka yakutshanje, ukusetyenziswa kwayo kuye kwafikelela kwi-700 yezigidi ze-square metres. I-Geotextiles eYurophu naseJapan nazo ziye zafumana uphuhliso olukhawulezayo, kusetyenziswa minyaka le malunga ne-400 yezigidi zeemitha zesikwere kwiminyaka yakutshanje. Phakathi kwazo, amalaphu e-spunbond angalukwanga athatha malunga ne-60% yee-geotextiles ezingalukwanga; Emva kweminyaka yee-1990s, iJapan yabona ukwanda okubonakalayo ekusetyenzisweni kwee-geotextiles. Phakathi kwee-geotextiles zaseJapan ezingalukwanga, ukusetyenziswa kwendlela ye-spunbond yeyona inkulu, ibalelwa malunga ne-60% yesixa sisonke se-nonwoven geotextiles, kwaye ikakhulu ilaphu le-PET spunbond.

I-geotextile kwilizwe lethu yaqala ekuqaleni kwe-1980, kodwa isixa esisetyenzisiweyo sasincinci kakhulu ngelo xesha, kwaye yayiyisicelo sokulinga. Kwakungekho de kwafika isikhukula esiyintlekele ka-1998 apho urhulumente wanikela ingqalelo kuyo, kwaye isebe lokwakha libandakanye ukusetyenziswa kwe-geotextiles kwiinkcukacha zoyilo kwaye lenze imigangatho yelizwe efanelekileyo apho i-geotextiles ifumene ingqalelo kunye nophuhliso. Okwangoku, ukusetyenziswa kwe-geotextiles e-China kudlule kwi-300 yezigidi zeemitha zesikwere, kwaye ii-geotextiles ezingalukwanga zithatha malunga ne-40% yetotali. Ulwakhiwo lobunjineli baseTshayina lunorhwebo olukhulu olunokubakho, olungekho ngaphantsi kosetyenziso lwangoku lwe-700-800 yezigidi zesikwere seemitha eUnited States. Iingcali ziqikelela ukuba i-geotextiles yaseTshayina iya kuqhubeka ikhula ngokuphindwe kabini kwiminyaka eli-15 ezayo, kunye ne-PET spunbond filament geotextiles ebonisa isantya sokukhula ngokukhawuleza.
