Ukuhlukaniswa, indlela yokuqina kanye nezimpawu zohlelo lokusebenza zabakhulu abavame ukusetshenziswa

Isingeniso se-01
I-Shimperer uhlobo lwezengezo lwe-hehelogical, olungakwazi ukuqina kuphela futhi luvikele ukugcwala ngesikhathi sokwakha, kodwa futhi luphinde lunikeze ukuhlanganiswa kwezakhiwo ezinhle kakhulu zemishini nokuqina kwesitoreji. I-Firener inezimpawu zemithamo emincane, ukuqina okusobala nokusetshenziswa okulula, futhi kusetshenziswa kabanzi kuzinkungu, izimonyo kanye nokudaya, ukululama kwamafutha, ukulungiswa kwesikhumba kanye nezinye izimboni.

Ama-Fireners ahlukaniswe ama-Systems ane-oly kanye namanzi ngokuya ngezinhlelo ezihlukile zokusebenzisa, futhi iningi labakhulu bangamakhompiyutha e-polymer.

Njengamanje, kunezinhlobo eziningi zabakhulu abatholakala emakethe. Ngokusho kokwakheka kanye nendlela yokwenza isenzo, ikakhulukazi ahlukaniswe ngezinhlobo ezine: izinqwaba, ama-cellulose, ama-polylacrlate kanye nabahlanganisi we-polyurethane.

02 Ukuhlukaniswa
I-Cellulosic Shilener
Ama-cellulosic amikhulu anomlando omude wokusebenzisa futhi kunezinhlobo eziningi, kufaka phakathi i-methyl cellulose, i-cardboxylopyl cellulose, i-hydroxypypropylllose, i-hydroxypropylllose, i-hydroxypropylll methyl cellulose, njll. Okusetshenziswa kakhulu kwalokhu kuyi-hydroxyethyl cellulose.

Indlela yokuqina:
Indlela yokuqina ye-cellulose nyorener ukuthi i-hydrophobic main chain kanye nama-molecule wamanzi azungezile ahlotshaniswa nama-hydrogen bond, anciphise isikhala sokunyakaza kwamahhala kwe-polymer uqobo futhi anciphise isikhala sokuhamba kwamahhala kwezinhlayiya, ngaleyo ndlela akhuphule ukubonwa kohlelo. I-Viscosity nayo ingandiswa ngokusebenzisa amaketanga ama-molecular, ikhombisa ukubonakala okuphezulu ku-static kanye ne-shear ephansi, kanye nokubonakaliswa okuphansi kokugunda okuphezulu. Lokhu kungenxa yokuthi ngamanani aphansi noma aphansi we-shear, amaketanga ama-cellulose molecular emazweni aphazamisekile, okwenza uhlelo lubonakale kakhulu; Ngenkathi usemazingeni aphezulu e-shear, ama-molecule ahlelwe ngendlela ehlelekile eqondana nendlela yokugeleza, futhi kulula ukuslayida nomunye, ngakho-ke ukubonakala kohlelo kuncipha.

i-polyacrylic mkhulu

I-Polyacrylic Acid Shikener, eyaziwa nangokuthi i-Alkali ukuvuvukala okukhulu (i-ASE), imvamisa i-emullion elungiselelwe yi (meth) acrylic acid kanye ne-ethyl acrylate nge-polymerization ethile.

Isakhiwo esijwayelekile se-Alkali-turen Shidener yile:

Indlela yokuqina Ngaphezu kwalokho, futhi kwakha isakhiwo senethiwekhi ngokubopha phakathi kwezinhlayiya ze-latex nemibala, yandisa ukubonwa kohlelo.

I-Polyurethane Polyurethane Emikhulu

I-Polyurethane Emikhulu, okubhekiselwa kuyo njenge-heur, iyi-polymer eguqulwe ngeqembu eliguqulwe nge-polyurethane lamanzi, okungokwalowo ongeyena u-ionic Associative Swenener. I-Heur yakhiwa izingxenye ezintathu: iqembu le-hydrophobic, i-hydrophilic chain ne-polyurethane group. Iqembu le-hydrophobic lidlala indima yenhlangano futhi liyisici esinqumayo sokuqina, imvamisa, i-octadecyl, i-dodecylphenyl, i-nonyphenol, njll. I-chain molecular of heur yenwetshwa amaqembu we-polyurethane, njenge-IPDI, i-TDI ne-HMDI.

Indlela yokuqina:

1) ukuphela kwe-hydrophobic kwe-molecule associates nezakhiwo ze-hydrophobic ezinjengezinhlayiya ze-latex, ama-surfactants, kanye nemibala yokwenza isakhiwo senethiwekhi enezici ezintathu, okubuye kube ngumthombo wokuvuleka okuphezulu kwe-shear;

2) Njengomuntu osontekile, lapho okuhlushwa kwamanje kuphakeme kunama-minelle abucayi, ama-michelles akhiwa, kanye nokubonakaliswa okuphakathi nendawo (1-100s-1) kuphethwe yiwo;

3) I-hydrophilic chain ye-molecule esebenza ngesibopho se-hydrogen se-molecule yamanzi ukufeza umphumela wokuqina.

I-Inorganic Shindener

Ama-inorganic amikhulu afaka phakathi i-carbon emhlophe emnyama, i-sodium bentonite, i-organic bentoni, umhlaba we-diatomaceous, i-attapulgite, isihlungo se-molecular, kanye ne-silica gel.

Indlela yokuqina:

Lapha, ethatha i-bentonite ye-organic njengesibonelo, indlela yayo yesimbozo imi kanjena:

I-Organic Bentonite imvamisa ayikho efomini lezinhlayiya eziyinhloko, kepha ngokuvamile iyisihlanganisi sezinhlayiya eziningi. Izinhlayiya eziyinhloko zingakhiqizwa ngenqubo yokumanzisa, ukusabalalisa kanye nokwenza kusebenze, kwakha umphumela osebenzayo we-thixotropic.

Ohlelweni lwePolar, i-polar activator ayinikezela amandla amakhemikhali ukusiza i-bentonite ye-organic ukuba isabalalise, kodwa futhi namanzi aqukethe athuthelwe eqenjini le-hydroxyl emaphethelweni ama-beftonite flakes ukuze athole. Bona, ngokubopha ama-molecule wamanzi, ama-bentonite angenakubalwa ama-flakes akha ukwakheka kwejeli, kanye namaketanga we-hydrocarbon e-flake indawo ekhula uhlelo futhi akhiqize imiphumela ye-thixotropic ngamandla awo aqinile wokuzilibazisa. Ngaphansi kwesenzo samandla angaphandle, isakhiwo siyabhujiswa futhi i-visa sincipha, futhi amandla angaphandle abuyela esimweni sokuqala. I-Viscosity Nesakhiwo.

03 Isicelo

I-cellulosic mkhulu cellulosic nyounener inokuqina okuphezulu okuphezulu, ikakhulukazi ngokuqina kwesigaba samanzi; Inemingcele embalwa kwizimbobo futhi isetshenziswa kabanzi; Ingasetshenziswa ebangeni elibanzi le-PH. Kodwa-ke, kukhona ababi abanjengokwezinga elibi, ukugaxeka ngokwengeziwe ngesikhathi sokuhlanganiswa kwe-roller, ukuzinza okungekuhle, futhi kusengozini yokuwohloka kwe-microbial. Ngoba inokubona okuphansi ngaphansi kwe-shear ephezulu nokubonakala okuphezulu ngaphansi kwe-static ne-shear ephansi, i-viscosity inyuka ngokushesha ngemuva kokugcoba, kepha ngakolunye uhlangothi, kungadala amandla amancane.

I-Polyacrylic acid Strimpener polyacrylic acid Strikener inamandla aqinile kanye nokulinganisa izakhiwo, ukuqina okuhle kwebhayoloji, kepha kuyazwela ngenani le-PH kanye nokuphikiswa kwamanzi ampofu.

Ukwakheka okuhlekisayo kwe-Associative Polyurener Shidener kubhujiswa ngaphansi kwesenzo se-Shear Force, futhi i-visa yehle. Lapho amandla we-shear enyamalala, ukubonwa kungabuyiselwa, okungavimba into ye-SAG kwinqubo yokwakha. Futhi ukululama kwalo kwe-viscosity kune-hysteresis ethile, evumelana nokufakwa kwezinga lefilimu yokuhlanganisa. Isisindo se-molecular esihlobene (izinkulungwane zamashumi ezinkulungwane) ze-polyurethane likhulu liphansi kakhulu kunesisindo se-molecular (amakhulu ezinkulungwane zezigidi) zezinhlobo ezimbili zokuqala zabakhulu, futhi ngeke zikhuthaze ukugeleza. Amanzi aphezulu aphezulu we-cellulose mkhulu azothinta ukumelana kwamanzi kwefilimu yokuhlanganisa, kepha i-polyurethane kakhudlwana inamaqembu ama-hydrophilic kanye ne-hydrophobic, futhi iqembu le-hydrophobic linokubumbana okunamandla nge-matrix yefilimu yokuhlanganisa. Kusukela izinhlayiya ze-latex zibamba iqhaza enhlanganweni, ngeke kube khona ukugcwala, ngakho-ke ifilimu yokuhlanganisa ingabushelelezi futhi ibe nokukhanya okuphezulu.

I-Inorganic Shidener Effener Firenener esekelwe emanzini inezinzuzo zokuqina okuqinile, i-Thixotropy enhle, uhla olubanzi lokuzivumelanisa nezimo ze-PH Inani, kanye nokuqina okuhle. Kodwa-ke, njengoba i-Bentoni ithi i-inorganic powder emunxuse enhle yokukhanya, inganciphisa kakhulu i-gloss surface gloss of film ye-coating futhi isebenze njenge-ejenti yokuthola imali. Ngakho-ke, lapho usebenzisa i-bentonite ku-latex ecwebezelayo, ukunakwa kufanele kukhokhwe ukulawula umthamo. I-Nanotechnology isibonile i-nanoscale yezinhlayiya ezingaphakathi, futhi futhi inikeze ama-inorganic amikhulu anezakhiwo ezintsha.
