Mvura-based stiffeners ndeye organic additives isinganyungudika mumvura, asi ine zvimwe zvinoomesa zvinhu (hapana ionic kana molecular cheni inoreba kusvika ku2 ~ 3 mazinga, hombe chaiyo nzvimbo). Ikirasi yemvura-based stiffener, inonyanya kushandiswa mupende, mapurasitiki, rabha, pendi uye mamwe organic coatings, adhesives uye mamwe maindasitiri. Stiffener ikirasi yezvigadzirwa zvehupenyu zvakaumbwa nehydrogenation yemapoka ester nenzira ye emulsions (ona Appendix A), stiffener inonyanya kuumbwa ne stearic acid (ester), hydroxyl mapoka (kunyanya mapoka ester), hydrogen bonds, hydroxyl, carboxyl uye amide mapoka. Kubatana kwehydrogen pakati pemapoka ester kunoguma nekukweva kana kuzvimba kweiyo stiffener. Nokudaro, iyo yakaoma inogona kubudirira kukurira kukanganisa kwekuputira uye kunamatira zvakadai sekukwinya, kuputsa kana kusvuura jira rekunamatira nekuda kwekuwedzera kwekushisa kwekushisa, uye ine yakanakisa kuchembera kupikisa uye asidi uye alkali kuramba, pamwe chete nemaitiro akanaka emagetsi, mamiriro ekunze uye kupisa kwekushisa uye kutonhora kwekudzivirira.
Stiffeners inogona kukamurwa kuita mapoka maviri, mafuta-anonyungudika uye anonyungudika mumvura, zvichienderana nechimiro chavo. Mafuta anonyungudika anoomesa anonyanya kushandiswa mune organic coatings akadai pendi, mapurasitiki uye rabha kudzivirira kuremara kwakadai sekuputika, kuputika uye kuputika kwezvinhu nekuda kwekuwedzera tembiricha. Mvura yakanyungudutswa yakaoma ine simba rekunyorovesa pane zvese zvinogadziriswa nemafuta nemvura uye haina kuputika pende, asi haiite zvachose nemusanganiswa wepigment kana kuita kuti ive nemakore uye zvimwe zvikanganiso. Somugumisiro webasa rekuomesera haribudisi ne-zvigadzirwa (zvakadai se acrylic kana sulphonate type) kana kuti kwete-zvigadzirwa, nokudaro kuvandudza kupararira kweiyo yakaoma mumiririri uye kuwedzera kuoma kwekugona kuvandudza zvakanyanya kupisa kwayo kupisa, kupikisa kwemamiriro ekunze, kutonhora kwechando uye kuderera kwekushisa kwekushanda. Iyo inoderedzawo huwandu hwekunyungudika hunoshandiswa mukuputira uye inowedzera nguva inodiwa pakuomeswa kweiyo mvura inoomesa stiffener, kuderedza mari yekugadzira.
Basic kemikari chimiro
Stiffener inowanzo umbwa neacetate, fatty acid esters, hydroxy acid ester compounds kana alkyl lipid compounds. Zvizhinji zvekuomesa zvinotora mvura uye nokudaro kuderedza viscosity ye stiffener system nekunyatsoparadzira organic solvents mu emulsion. Inogonawo kushandiswa se stabilizer kana emulsifier. Stiffeners inowanikwawo mumhando dzakakosha dzekuita. Zvakadai se: solvent-based hardener inoshandiswa mumapurasitiki, rabha, machira, adhesives uye mamwe maindasitiri; solvent-based hardener inoshandiswa mumapende uye machira ane maitiro akanaka ekuomesa; mvura inoshandiswa muindasitiri yezvekudya kuchengetedza kugadzirwa kwakanaka; insoluble mumvura, soluble in acrylates uye mamwe organic solvents; inogona kuwirirana neakawanda organic solvents; inogona kuburitsa hydrogen bonding nemaasidhi nemabhesi; simba chelating simba reasidhi anhydride ionic simba; inogona kushandiswa nemhando dzakasiyana dzepolymerization; yakanaka weatherability; kuoma kwepamusoro uye kusagadzikana kwemarara.
Stiffener kushandisa nzira
1, Kukurudzira: Stiffener mumusanganiswa ichaonekwa yakawanda yakaungana, mukuvhenganisa uye kunyandura nzira kuti ibudise chiitiko chemafuro, uye yakawandisa yakaturikwa nyaya, zvinozoita kuti paumbwe emulsion firimu pamusoro pepende uye kukonzera murombo stiffening effect uye mamwe matambudziko. Nokudaro, kuchenjerera kunofanira kubhadharwa kuhuwandu hwekuoma, huwandu hwekuwedzera hunofanira kunge hwakakodzera, musanganiswa haufaniri kunge wakanyanyisa, kuitira kuti urege kupararira zvisina kuenzana zvichikonzera kuputika, kukanganisa kushandiswa kwechiitiko.
2, kubvongodza: kushandiswa kweyepasi-speed inosimudzira midziyo kugadzira iyo stiffener hydration uye kuumbwa kweiyo yunifomu kuenderana kwemusanganiswa wemvura, iyo nzira ine zvinotevera: (1) tanga wawedzera kuderera kweiyo stearic acid (ester), hydroxyl, hydrogen bonding uye hydroxyl, uyezve yakasanganiswa ne stearic acid kana ester mapoka; Kana izvo zviviri pamwechete zvive musanganiswa unoomesa; mushure mekuwedzera huwandu hwakakodzera hwemvura uye kudziyisa kuti iite denature.
3, solvent-based: iyi mhando yekuomesera ikirasi ye organic compounds kana mapolymers akavakirwa pacarboxyl (kana hydroxyl); yakanyungudika mumvura uye yakagadzira copolymer (kazhinji ester-based) chimiro; kana kuti polymerization yayo kuti iwane kureba kwema molecular cheni, yakakura chaiyo nzvimbo, yakakwirira viscosity uye yakanaka dispersion properties uye mumvura-based The cross-linked structure is polymer ine yakareba molecular chain, yakakura chaiyo nzvimbo, yakakwirira viscosity uye yakanaka dispersion properties uye chimwe chisungo chiri mumvura inoputira system (zvikurukuru zvichienderana nehuwandu hwe restiffener system). Stiffeners imulsion-sezvinwiwa zvinonyudzwa patembiricha yekamuri uye zvinogadzira network network mushure mekutevedzana kwemaitiro (ona appendices A uye B). MaStiffener anowanzo aine zvidiki zvidiki zvezvinowedzerwa zvakaita semunyu, carboxylic acids (eg hydroxyl amines, phosphate esters kana disodium sulphonates) kana zvidiki simbi ions.
Hurongwa hwayo hwekushandisa hwakapamhama kwazvo, hunosanganisira mabhanditi emvura, mafirimu epurasitiki, zvinonamira uye mapolymer ane hardener anogona zvakare kushandiswa sehwaro hwezvinhu zvekupfeka kana zvigadzirwa zvepurasitiki.
1, mvura-yakavakirwa kana mafuta-yakavakirwa: yakakodzera kune ese marudzi ekupfeka, kazhinji epakati-renji zvigadzirwa; 2. isina-mvura yakasvibiswa: inogona kunyungudutswa mumvura uye zvishoma nezvishoma yakapararira mu emulsion yakaenzana yakapararira.
3, solid-phase mixing: emulsion liquid inogona kuwedzerwa kune akasiyana organic adhesives pamwe neSolid material inosanganiswa zvakanaka (ine organic fillers) yekusanganisa; kuwedzera chiyero chakakodzera chekuomesera kuchaita kuti iyo yakaoma ive nehumwe hurema hwekuvandudza ma mechanical properties uye kuramba kuchembera (ona Appendix B).
- Waterborne stiffener coatings pamwe
Stiffener mune organic coatings, mapurasitiki, rabha uye mamwe maindasitiri
Stiffener mumvura-based coatings inonyanya kushandiswa kugadzirisa unsaturated polyesters, copolymer emulsions, etc. Inogona kuita kuti synthetic resin performance ivandudzwe. Iyo polymer mushure mekuoma haingove nemhando yepamusoro kuoma, asiwo ine nani kudzivirira mvura uye kuramba kuchembera. Inogona kushandiswa nekutanga diluting iyo stiffener mumhinduro ine mutsara we 20-40%, wozoiwedzera kune reactor ye emulsification reaction uye kuwedzera huwandu hwakakodzera hwe dilution kuti iite yakanyanya kuomesa emulsion. Kana iyo emulsion iine inopfuura imwe muzana ye organic solvents, chiitiko chepolymerization uye kuora chichaitika, izvo zvisingangodzikisi kuita kweresin asiwo zvinokonzeresa kuchembera kwemidziyo kana chigadzirwa. Saka mukugadzirwa kwejasi uye mapolymer masisitimu ekuwedzera huwandu hwakakodzera hwekuomesera kunogona kuvandudza kushandiswa kwemhedzisiro yayo, kuitira kuti chigadzirwa ive nani kuchinjika uye yakakwirira tembiricha kuramba.
