Upfu hwepolymer hunonyungudika (RDP), sechikamu chikuru che organic mu dry-mix mortars dzemazuva ano, inoshandiswa zvakanyanya mumhando dzakasiyana-siyana dzakadai se tile adhesives, putty powders, exterior wall insulation mortars, self-leveling mortars, uye waterproof mortars nekuda kwehunhu hwayo hwakanaka hwekubatanidza, kuchinjika, uye kugona kwayo kugadzirisa. Chaizvoizvo, ihupfu hwakasimba hunogadzirwa nekupfapfaidza-kuomesa polymer emulsion. Kana yasangana nemvura, inogona kupararira zvakare kuita stable emulsion, nokudaro ichigadzira organic polymer film inoramba iripo panguva yekuomesa mortar, zvichivandudza zvakanyanya mashandiro ese emortar.
1. Nzira huru yeRDP mukuvandudza mashandiro eMortar
1.1. Kuvandudza Simba reBond
Firimu repolymer rinoumbwa neRDP mushure mekuomeswa kwemortar rine kunamatira kwakanyanya uye ductility yakanaka, richigadzira bhiriji rakasimba rekubatanidza pamusoro pesubstrate, zvichivandudza zvakanyanya kunamatira pakati pemortar nezvinhu zvakaita sekongiri, zvidhinha, mabhodhi eEPS, nemataira. Basa reRDP rakakosha zvikuru pasubstrate dzisinganyanyi kunyorova kana kuti dzakapfava.
1.2. Kuchinjika Kwakawedzerwa uye Kuramba Kutsemuka
Zvinhu zvechinyakare zvakagadzirwa nesimende zvinopfava uye zvinogona kutsemuka nekuda kwekuchinja kwetembiricha uye kushanduka kwesubstrate. Iyo polymer iri muRDP inopararira mumortar pores, ichigadzira chimiro chenetwork chinochinjika, ichideredza elastic modulus yezvinhu, uye inowedzera kuramba kwayo kushanduka, nokudaro ichivandudza zvakanyanya kuramba kwemortar kuputika.
1.3. Kushanda Kwakavandudzwa
RDP inoita kuti dhaka rive rakatsetseka uye rakapfava, zvichivandudza kushanda uye kunzwa kwekushandisa. Kuchengetedzwa kwaro kwemvura uye nguva yakareba yekuvhura zvinoita kuti kuvaka kuve kwakatsetseka, zvichiwedzera kushanda zvakanaka uye kugadzikana kwemhando.
1.4. Kudzivirira Mvura Nemamiriro Ekunze Kwakawedzerwa
Firimu repolymer rine hunhu hwakanaka hwekusapindirana nemvura uye hunodzivirira mvura, zvichideredza kunyudzwa kwemvura mudura uye zvichivandudza kupindirana kwemvura uye kunyungudika kwechando. Mukushandiswa kwemadziro ekunze, RDP inobatsira kuvandudza kupindirana kwemamiriro ekunze kwezvipfeko nemadura, zvichichengetedza kugadzikana kwazvo kana zvagara kwenguva refu.
2. Kushandiswa kweRedispersible Polymer (RDP) muMasisitimu Akasiyana eMortar
2.1. Kunamira Mataira
RDP chinhu chakakosha pakunamira mataira, zvichivandudza zvakanyanya kunamira, hunhu husingatsvedzeri, uye kuchinjika. Kune mataira makuru, mataira asinganyanyi kunyudzwa, kana mataira ane vitrified, RDP ine polymer yakawanda inoita kuti pave nekusungana kwakasimba uye inodzivirira nzvimbo dzisina maburi uye kupatsanuka.
2.2. Dura rekudzivirira madziro ekunze (EPS/XPS Adhesive, Dura rekugadzirisa)
Mumasisitimu ekudzivirira kupisa, RDP inopa kuchinjika kunodiwa uye simba rekubatanidza, zvichibvumira kuti dhaka rinamire zvakasimba pamapuranga eEPS/XPS. Inovandudzawo kuramba kutsemuka uye kuramba kukanganiswa kwechikamu chekupedzisira, zvichiita kuti sisitimu yekudzivirira kupisa igare yakasimba kwenguva refu.
2.3. Dura Risingapindi Mvura
RDP inoumba firimu repolymer rakakora mukati memota, ichideredza kuyerera kwema capillary uye inovandudza kusapinda kwemvura. Ichishanda pamwe chete nezvigadzirwa zve hydration yesimende, inowedzera zvakanyanya kuchinjika uye kugara kwenguva refu kwechikamu chisingapindi mvura.
2.4. Dura Rinozvienzanisa
Muhurongwa hwekuzvienzanisa, RDP inovandudza simba rekutanga, kuyerera, uye hunhu hwekubatanidza kwedhaka uku ichideredza kuputsika, zvichikonzera kuvakwa kwepasi kwakasimba uye simba repamusoro.
2.5. Upfu hwePutty
Kuwedzera RDP mupudhi yeputty kunowedzera kunamira, hunhu hwekudzivirira kutsvedza, uye kunzwa kwekutsvedza, zvichiita kuti madziro ave akapfava, akanyatsonaka uye arambe akasimba uye anodzivirira mvura.
2.6. Kugadzirisa Mortar uye Interface Agent
RDP inovandudza kunamira uye kuramba kutsemuka kwezvinhu zvekugadzirisa, zvichiita kuti zvive zvakagadzikana uye zvakavimbika mukushandiswa kwakadai sekugadzirisa kongiri yekare uye kugadzirisa interface.
3. Nzira dzekudzivirira pakushandisa Upfu hwePolymer Hunonyungudika
Sarudza yakakodzeraRDPmhando uye chiyero chakavakirwa pakushanda kwesystem yedhaka;
Kusanganisa ne cellulose ethers (HPMC/MHEC), starch ethers, nezvimwewo, kunogona kuwedzera kuchengetedza mvura, kushanda zvakanaka, uye kuramba kudonha kwemvura;
Chengeta munzvimbo yakaoma kudzivirira hunyoro uye kuungana kwevhu;
Iva nechokwadi chekuti mvura yacho yakapararira zvakanaka panguva yekusanganisa kuti ishande zvakanaka.
