Impahla ye-polyester engalukiwe

Indwangu engalukiwe ye-polyester spunbond inamandla aphezulu, ukumelana kahle nezinga lokushisa eliphezulu (ingasetshenziswa isikhathi eside endaweni engu-150 ℃), ukumelana nokuguga, ukumelana ne-UV, ubude obuphezulu, ukuqina okuhle nokuphefumula, ukumelana nokugqwala, ukugqumisa umsindo, ukumelana nebhu, nokungabi nobuthi.

Izici zezinto ezingavuthiwe

1. Imicu ye-polyester inokumelana okuhle kakhulu nokushwabana, ukunwebeka, nokuzinza kwe-dimensional, kanye nezakhiwo ezinhle zokuvala ugesi. Azikwazi ukumelana nokukhanya kwelanga, ukungqubuzana, isikhunta nokubola. Futhi banokumelana okuhle nama-reagents amakhemikhali futhi bangakwazi ukumelana nama-acids abuthakathaka nama-alkali.

2. Emazingeni okushisa asekamelweni, inekhono elithile lokumelana nama-acids ahlanjululwe futhi aqinile, kodwa ukumelana kabi ne-alkalinity enamandla.

3. Ukusebenza kokudaya kwemicu ye-polyester kubi, futhi ngokuvamile kudingeka kudayiwe ngodayi abahlakazekile emazingeni okushisa aphezulu noma lapho kukhona abathwali.

Ukusetshenziswa kwendwangu engalukiwe ye-polyester

1. Isetshenziselwa ukuhlobisa kwangaphakathi, indwangu yesisekelo sikakhaphethi, indwangu yemboni yezemithi, i-fluff, i-lining, njll.

2. Isetshenziselwa ukwakhiwa, ukuvimbela amanzi ophahleni kusebenza njengendwangu yesisekelo, nesihlabathi, usimende, njll.

3. Isetshenziswa ekwakheni, kuyisinyathelo esithathwayo ukuvimbela imifantu.

4. Ngokwezici zokuguga kanye nezici zokumelana nokushisa okuphezulu kwezindwangu ezingezona ezilukiwe ze-spunbond, zisetshenziswa kakhulu ezindwangu zasekhaya, izinto eziyinhlanganisela, izinto zemithwalo, njll. Futhi ngenxa yokumelana kwayo nokuguga; Kuqashelwa kakhulu abathengi.

Imakethe yendwangu engalukiwe ye-polyester spunbond

Ukusetshenziswa kwe-geotextiles emazweni angaphandle kwaqala ekuqaleni kwawo-1960. I-United States iyizwe elisetshenziswa kakhulu i-geotextiles emhlabeni. Ekuqaleni kwawo-1990, ukusetshenziswa kwayo ngonyaka kwakungaphezu kwamamitha-skwele ayizigidi ezingu-300, futhi eminyakeni yamuva nje, ukusetshenziswa kwayo sekufinyelele ku-700 million square metres. I-Geotextiles eYurophu naseJapan nayo ithuthuke ngokushesha, ngokusetshenziswa konyaka cishe kwezigidi-skwe zamamitha angama-400 eminyakeni yamuva nje. Phakathi kwazo, izindwangu ezingalukiwe ze-spunbond zenza cishe u-60% wama-nonwoven geotextiles; Ngemuva maphakathi nawo-1990, iJapan yabona ukwanda okukhulu ekusetshenzisweni kwama-geotextiles. Phakathi kwama-geotextile aseJapane angalukwanga, ukusetshenziswa kwendlela ye-spunbond inkulu kakhulu, kubala cishe u-60% yenani eliphelele lama-nonwoven geotextiles, futhi ikakhulukazi indwangu ye-PET spunbond.

I-geotextile ezweni lakithi yaqala ekuqaleni kwawo-1980, kodwa inani elisetshenzisiwe lalincane kakhulu ngaleso sikhathi, futhi kwakuyisicelo sokuhlola kuphela. Kwaze kwaba yizikhukhula eziyinhlekelele zika-1998 lapho uhulumeni anaka khona, futhi umnyango wezokwakha wafaka nokusetshenziswa kwe-geotextiles emibhalweni yokuklama futhi wenza amazinga afanele kazwelonke lapho i-geotextiles yathola ukunakwa nokuthuthuka ngempela. Njengamanje, ukusetshenziswa kwama-geotextiles e-China kweqe ama-square metres ayizigidi ezingama-300, kanti ama-geotextiles angalukiwe athatha cishe u-40% wengqikithi. Ukwakhiwa kobunjiniyela baseChina kunemakethe enkulu engaba khona, engekho ngaphansi kokusetshenziswa kwamanje kwamamitha-skwele ayizigidi ezingama-700-800 e-United States. Ochwepheshe balinganisela ukuthi i-geotextiles yase-China izoqhubeka nokukhula ngamadijithi aphindwe kabili eminyakeni engu-15 ezayo, kanti i-PET spunbond filament geotextiles ebonisa izinga lokukhula ngokushesha kakhulu.
