Ngaba i-hydroxythlcelcelcelsed

I-HYDROXYETHLLCELXULOse (hec) yi-polymer engeyiyo i-ionic, i-poly-allmer esuswe kwi-sellyulose. Iqhelekile isetyenziswa kumashishini ahlukeneyo njengamayeza, amayeza, ukutya, kunye neemveliso zononophelo lomntu ngenxa yokutsalwa kwayo, ukuzinza, kunye neepropathi zokulungisa.

Isakhiwo sekhemikhali seHydroxyEstlcelcelcelcelcelose

I-HEC yi-sellsase i-sellulose, apho amaqela e-hydroxethyl azaziswa kwi-selsebose i-sellose. Olu hlengahlengiso luphucula ukubethwa kwamanzi kunye nezinye iipropathi zesellum. Amaqela e-hydroxyk Olu hlengahlengiso lutshintsha iipropathi zomzimba kunye neekhemikhali zesellose, zenza ilungele uluhlu olubanzi lwezicelo.

Iimpawu zokudakumba

I-1. Ukudibana

I-Selelose emsulwa yindawo enokutsha kuba iqulethe amaqela e-hydroxyl, enokufumana i-chassotion. Nangona kunjalo, ukungeniswa kwee-hydroxyl amaqela kwi-selselose wackbnene atshintsha iimpawu zalo zokudakumba. Ubukho bamaqela e-hydroxyyl kunokuchaphazela indlela yokuziphatha ye-hec ye-hec xa kuthelekiswa neselmose engekhonzileyo.

I-2. Uvavanyo lokuFumaneka

Uvavanyo lokudakumba lubalulekile ukumisela ingozi yomlilo ehambelana nomxholo. Iimvavanyo ezahlukeneyo ezisemgangathweni, ezinjenge-ASTM E84 (indlela yovavanyo esemgangathweni yeempawu zezinto zokwakha) kunye ne-UL 94 (imigangatho yokhuseleko), zisetyenziselwa ukuvavanya ukuvutha i-flamm. Ezi mvavanyo zovavanyo zivavanya iiparamitha ezifana nelangatye, uphuhliso lomsi, kunye neempawu zokufunda.

Izinto ezichaphazela ukuvutha

1. Umxholo wokufuma

Ubukho umswakama bunokuphembelela ukuvutha kwezinto. Izixhobo zeSelsulonsc zihlala zivutha kabini xa zinamanqanaba aphezulu omswakama ngenxa yokufunxa kobushushu kunye nefuthe lokupholisa kwamanzi. I-HYDROXDYETHLLCELXUlose, ukuba inyibiliza yamanzi, inokuba nexabiso lokufumanisa ukufuma ngokuxhomekeke kwimiba yendalo esingqongileyo.

I-2. Ubungakanani be-sucricle kunye nobunzima

Ubungakanani bentsebenzo kunye nokuxinana kwesixhobo kunokuchaphazela ukuvutha kwayo. IZAKHONO ZAMALUNGISELELO OQOQOSHO KAKHULU KUPHELA INDAWO YOKUGQIBELA, EKhuthaza ukudibanisa okukhawulezileyo. Nangona kunjalo, i-HEC isetyenziswa ngokuqhelekileyo kwifom eqingqiweyo okanye ye-GORED nge-particle elawulayo yokufezekisa iimfuno ezithile zesicelo.

3. Ubukho bezongezo

Kwizicelo ezisebenzayo, i-hydroxythylcelcelcelces isenokuqulatha izithintelo ezifana nezithintelo ezifana neplastiki, ukuzinza, okanye ukulungisa ilangatye. Ezi zongezo zinokutshintsha iimpawu ezivuthayo zeemveliso ezisekwe kwi-hec. Umzekelo, ukuzigcina kwelangatye kunokubacinezela okanye ukulibazisa ukumiswa kunye nokusasazeka kwamadangatye.

Ingozi yomlilo kunye nokuqwalaselwa kukhuseleko

1. Ukugcina kunye nokuphatha

Ukugcina ngokufanelekileyo kunye nokusebenzisa izinto kubalulekile ukunciphisa umngcipheko wezehlo zomlilo. I-HydroxyEstlcelcelcelselly kufuneka igcinwe kwindawo eyomileyo, ecocekileyo kude nemithombo enokubakho. Inkathalo kufuneka ithathwe ukuthintela ukuvezwa kobushushu obukhulu okanye ukukhanya kwelanga ngokuthe ngqo, okunokukhokelela kwi-DOROCATION okanye i-Igs.

2. Ukuthobela umthetho

Abavelisi kunye nabasebenzisi bee-hydroxylcelcelcelose-ezinemveliso ekufuneka zihambelane nemigaqo efanelekileyo yokhuseleko. Amaziko olawulo anjengoLawulo lweMsebenzini kunye noLawulo lwezeMpilo (Osha) e-United States kunye ne-Arhente ye-Afrika yaseYurophu) kwi-European Union ukubonelela ngesikhokelo sokuphatha okukhuselekileyo kunye nokusetyenziswa kweekhemikhali.

I-3. Iindlela zokucinezelwa komlilo

Kwimeko yomlilo ebandakanya i-hydroxythlcelcelcelcelose okanye iimveliso eziqukethe i-HEC, amanyathelo afanelekileyo oxinzelelo lomlilo kufuneka aphunyezwe. Oku kunokubandakanya ukusebenzisa amanzi, i-carbon diokside, ukucima ikhemikhali emichiza, okanye i-foam, kuxhomekeke kubunjani bomlilo kunye nendawo engqongileyo.

I-HYDROXYETHLLCELCULOse sisimo se-sellulose eguqulweyo esetyenziswayo kumashishini ahlukeneyo ukuze aqaqambe kwaye azinzile. Ngelixa i-sellyulose icocekileyo iyavutha, ukumiliselwa kwamaqela e-hydroxyyl kuguqula iimpawu ze-hec. Izinto ezifana nomxholo wokufuma, ubungakanani be-suricle, uxinzelelo, kunye nobukho bamanqaku ongezelelweyo kunokuphembelela ukuvutha kwemveliso ye-hydroxylcelose-enemveliso. Ukugcina ngokufanelekileyo, ukuphatha, kunye nokubambelela kwimigaqo yokhuseleko kubalulekile ukunciphisa iingozi zomlilo ezinxulumene ne-hec. Olunye uphando kunye novavanyo lunokuba yimfuneko ekuqondeni ngokupheleleyo indlela yokuziphatha evuthayo ye-hydroxylcelose phantsi kweemeko ezahlukeneyo kunye nefomu.
