Ngophuhliso lwesayensi kunye nethekhinoloji kunye nokuphuculwa kwenqanaba lokusetyenziswa, imfuno yeemveliso ezisebenzayo zamalaphu ikwabonisa indlela ekhulayo unyaka nonyaka. Njengoko sonke siyazi, eminye yemisebenzi yeemveliso ze-textile idla ngokuqondwa ngendwangu emva kokugqiba ukusebenza, phakathi kwayo umsebenzi ongenamanzi unikezelwa ngeempawu zokungena kwamanzi zendwangu emva kokugqiba.

Okubizwa ngokuba kukugqiba ukuchaneka kwamanzi, kubhekiselele ekusebenziseni indlela yokugqiba kumphezulu welaphu ukwenza umaleko wesakhiwo soxinzelelo oluphantsi, ukuze umphezulu welaphu ukusuka kutshintsho lwe-hydrophilic ukuya kwi-hydrophobicity, kodwa kwakhona ugcine iimpawu zokuqala zentsebenzo. ilaphu. Ilaphu elingangeni manzi liyathandwa ngabathengi kuba alichaphazeli ukunxiba. Imfuno yamalaphu asebenzayo angangeni manzi kwiimarike zasekhaya nakwamanye amazwe iyanda unyaka nonyaka. Izixhobo zokugqiba amanzi ezikhethiweyo ezikhethiweyo kwiindwangu zibandakanya i-agent engenamanzi kunye ne-oyile yokugqiba i-oyile equkethe isakhiwo se-fluorocarbons kunye ne-fluorine-free-free waterproofing agents ezikhethwe ngabathengi abaninzi.

Kuba akukho ndlela isebenzayo yokusombulula uhlobo lwehlabathi lwe-fluorocarbon yearhente yokuthintela amanzi i-perfluorinated octane (PFOS) kunye ne-perfluorinated sulfonyl compounds octylic acid (PFOA) inokubangela isifo kumzimba wesilwanyana ekuqokeleleni okuyityhefu kwaye ichaphazele iingxaki zendalo, njengaxa i-eu. Izithintelo, amazwe awasayi kuqhubeka nokuvelisa uhlobo olude lwe-fluorocarbon ikhonkco elide le-C8 ye-agent yokugqiba amanzi, Ke ngoko, ukufumana iimveliso zokungangeni manzi ngaphandle kwe-PFOS kunye ne-PFOA ye-surfactants iye yaba yingqwalasela yezongezo zeshishini kunye nabathengi.

Ngasekupheleni kwenkulungwane yama-20, iUnited States, iJapan kunye namanye amazwe benza uphando olunzulu malunga ne-fluorine-free waterproofing agent, kwaye bapapasha ngokulandelelana amalungelo awodwa omenzi wechiza kwi-arhente yokugqibezela engena manzi ngefluorine. Ukusuka kwindawo yokujonga ukukhuselwa kwendalo kunye nokhuseleko, ngokude nje ukuba i-agent yokugqiba amanzi ngaphandle kwe-fluorocarbon resin ingabizwa ngokuba yi-fluorine-free waterproofing agent. I-fluorine-free-free-filling agents ingenawo nayiphi na i-PFOS kunye ne-PFOA, ayiyi kufakwa kumzimba wezinto eziphilayo, kwaye kulula ukuthotywa. Ke ngoko, ngombono okhulayo wokuthandwa kwe-ecology, ukhuseleko lokusingqongileyo kunye nempilo, ii-agent ezingenayo i-fluorine ezigqibezela amanzi zimkelwa ngokulula ngabathengi kunye nentengiso njengohlobo lweemveliso ezikhuselekileyo kunye nokhuseleko lokusingqongileyo.

Okwangoku, i-ejenti yokugqiba i-fluorine engenamanzi eveliswa ziimpawu zangaphandle ezifana ne-Huntsman, i-3M, i-Nano-Tex, i-Rudolf kunye nezinye iinkampani ziye zadlula uvavanyo olungqongqo lokusebenza kokukhusela okuluhlaza kunye nokusingqongileyo, kwaye inokubonelela abathengi nge-fluorine yabo engenamanzi. i-arhente yokugqiba yokusetyenziswa kwimpahla kunye nezinye iimveliso zamalaphu. Ngexesha elifanayo ukuphucula ixabiso le-brand yeemveliso ze-terminal ukudala ingcamango ye-ecological eluhlaza. U-Huntsman wazisa i-ZELAN?, isiphelo se-fluorine, esinganyangekiyo ngamanzi esenziwe nge-60% yemathiriyeli esekwe kwizityalo. I-R3, imveliso ifumene umgangatho we-Swiss Blue wokhuseleko lwelaphu lokusingqongileyo

(Bluesign?). Ukuqinisekiswa, kunokubonelela ngesiphumo sokungangeni kwamanzi kwiintlobo ezahlukeneyo ze-textile substrates; Yasungula enye ye-fluorine-free arhente yokuthintela amanzi PHOBOL RSH ingafakwa ngokwahlukileyo kwifayibha eselulosi kunye nefayibha eyenziwe ngelaphu elidityanisiweyo lokuthintela amanzi, inokusebenzisa i-agent engangeni manzi kunye ne-fluorocarbon yokugqiba iarhente, ukuze kuncitshiswe i-fluoride engenamanzi, ukuthintela umxholo weoyile, emva kokugqiba iimpahla ezilukiweyo zinefuthe elihle kakhulu lokungangeni manzi, zithintele ioyile, ukusebenza kakuhle komoya wokungena komoya ngaxeshanye, Kwanakwinkqubo yokuzilolonga kunokugcina iimpahla zomile, azichaphazeli ukubila komzimba womntu.

I-Rudolph's ECO uhlobo lwe-bionic non-fresno i-agent yokuthintela amanzi luhlobo lokungaqulathanga i-organic halide kunye ne-alkyl phenol polyoxyethylene ether compounds (APEO) ye-hyperbranched tree macromolecular compounds kunye ne-polymers, inokusetyenziswa njengamalaphu aphezulu angangeni manzi eentlobo ezahlukeneyo zokugqiba ifayibha. iarhente, kunye nesiphumo sesicelo sayo kunye nokukhuselwa kwendalo kokusingqongileyo kweemveliso ezivunywe ziimpawu ezininzi ezidumileyo zehlabathi.

I-agent ye-fluorine engenamanzi yokugqiba i-X018 evela kwinkampani yaseMelika ye-Nano-Tex yi-ejenti ehlala ixesha elide yokugqiba i-hydrocarbon polymer structure. Ilungele ukugqitywa komqhaphu ongenamanzi, Polyester, Umtya kunye namanye amalaphu, kwaye anokusetyenziswa kunye ne-nT-X628 i-synergist engangeni manzi equlethe isakhiwo se-resin esebenzayo ukunyusa ukuqina kokugqitywa kwamanzi kwamalaphu.

I-DAIKIN fluorine-free waterproofing agent agent egqibezela itekhnoloji yokulungiswa kwetyathanga elisecaleni kunye netekhnoloji entsha yokwahlulwa komhlaba, eyenza ukuba icandelo lekristale ye-hydrophobic iqokelele kumaleko angaphandle, inciphisa ukuxinana komphezulu welaphu elingangenwa manzi, kunye nokuphucula ukumelana nokuhlanjwa kunye nentuthuzelo ngelixa uqinisekisa isiphumo sokungena manzi kwemveliso.

Isiphelo se-Archroma's fluorine-free waterproof finishing, i-Arkophob FFR PFC-free, iqulathe iikhompawundi ezinamafutha alungisiweyo kunye ne-alkane dispersions esetyenziswa ekugqityweni kobungqina bemvula be-cellulose kunye nemixube yefayibha zokwenziwa.

Kwiminyaka yakutshanje, abavelisi abaninzi abancedisayo basekhaya, abanje ngeChuanhua Chemical, iDemei Chemical, iZhongfang Chemical, iDeco Nano, baye basungula iarhente yokugqiba i-fluorine engenamanzi enesiphumo esihle. Kukholelwa ukuba ngokuqhubekayo uphando olunzulu kunye nophuhliso lwe-agent ye-fluorine-free waterproofing agent, umphumo wesicelo se-fluorine-free waterproof agent iya kuqhubeka nokuphucula, kwaye imfuno yayo yemarike iya kuqhubeka ikhula.

Ngolwazi oluthe kratya, nceda ubeke ingqalelo kwinqaku elithi "Imeko yesicelo kunye neNdlela yoPhuhliso yeFluorine-free waterproof Finishing Agent", i-Textile Herald, iNombolo yesi-3, i-2022.
