Iyo ibikoresho bishingiye kuri sima byongewemo ifu ya latex bihuye n'amazi, imiterere y'amazi iratangira, maze umuti wa calcium hydroxide ugera vuba ku rugero rw'amazi maze kristu zigahinduka, kandi icyarimwe, kristu za ettringite na silikalike hydrate gels ziraremwa. Uduce duto dushyirwa kuri gel n'uduce twa sima tudafite amazi. Uko imiterere y'amazi ikomeza, imiterere y'amazi iriyongera, kandi uduce twa polymer tugenda duteranira mu myenge y'imiyoboro, dukora urwego runini ku buso bwa gel no ku duce twa sima tudafite amazi.
Uduce twa polymer twakusanyijwe twuzuza buhoro buhoro utwenge, ariko ntabwo tugera ku buso bw'imbere bw'imyenge. Uko amazi arushaho kugabanuka bitewe no kumena cyangwa kuma, utwo duce twa polymer twafatanye kuri gel no mu myenge duhurira hamwe mu firime ikomeza, dukora uruvange rw'amazi hamwe na sima yatose kandi binoza amazi. Guhuza ibicuruzwa n'ibice byakusanyijwe. Kubera ko ibikomoka ku mazi hamwe na polymer bikora urwego rutwikira aho bihurira, bishobora kugira ingaruka ku mikurire ya ettringite na calcium hydroxide crystals; kandi kubera ko polymers zivangavanze mu myenge y'aho bihurira, ibikoresho bishingiye kuri polymer sima Akarere k'aho bihurira karakomeye. Amatsinda akora muri molecule zimwe na zimwe za polymer azatanga reactions cross-linked na Ca2+ na A13+ mu bikoresho bya polymer hydration kugira ngo habeho imigozi yihariye, kunoza imiterere y'ibikoresho bishingiye kuri sima ikomeye, kugabanya stress imbere, no kugabanya ikorwa ry'udusimba duto. Uko imiterere ya gel ya sima ikura, amazi arakoreshwa kandi utwo duce twa polymer tugenda dufungana buhoro buhoro mu myenge. Uko sima irushaho kunyurwa, ubushuhe buri mu myenge y'imiyoboro igabanuka, kandi uduce twa polymer twishyira hamwe ku buso bw'umuvuduko w'isima uvanze na sima idafite amazi n'uruvange, bityo bigakora urwego ruhoraho rufite imyenge minini. Rwuzujwemo uduce twa polymer dufata cyangwa twifata.
Uruhare rw'ifu ya latex ishobora gusubirwamo mu gishishwa rugenzurwa n'uburyo bubiri bwo gutonyanga sima no gukora firime ya polimeri. Ikorwa ry'uburyo buhuriweho bwo gutonyanga sima no gukora firime ya polimeri rirangizwa mu ntambwe 4:
(1) Nyuma y'uko ifu ya latex ishobora gukurwamo ivanzwe na sima, ikwirakwizwa neza muri sisitemu;
(2) Uduce twa polymeri dushyirwa ku buso bwa gel y'umusaruro wa sima/uruvange rw'uduce twa sima tudafite amazi;
(3) Uduce twa polymeri dukora urwego rukomeza kandi rufatanye;
(4) Mu gihe cyo gutonyanga sima, uduce twa polymer twafatanye cyane twishyira hamwe mu buryo bukomeza, tugahuza ibikoresho byo gutonyanga hamwe kugira ngo bibe imiterere yuzuye y'urusobe rw'amazi.
Ifu ya latex isubiranywa ishobora gukora firime idashonga mu mazi (umuyoboro wa polymer) nyuma yo kuma, kandi iyi firime ya polymer modulus yoroshye ishobora kunoza imikorere ya sima; icyarimwe, muri molekile ya polymer. Amatsinda amwe ya polar muri sima akorana na shimi n'ibicuruzwa bya sima kugira ngo akore ibiraro byihariye, anonosore imiterere y'ibicuruzwa bya sima, kandi agabanye no kugabanya ivuka ry'imivuniko. Nyuma yo kongeramo ifu ya latex isubiranywa, igipimo cy'amazi cya sima kiragabanuka, kandi firime ya polymer ishobora gupfunyika ibice bya sima igice cyangwa burundu, kugira ngo sima ibashe kunyurwa neza kandi imiterere yayo itandukanye ishobore kunozwa.
Ifu ya latex ishobora guhindurwa ifite uruhare runini nk'inyongera ku gikoresho cyo kubaka. Gushyira ifu ya latex ishobora guhindurwa mu gikoresho cyo kubaka bishobora gutegura ibintu bitandukanye bya sima nka kole y'amatafari, sima irinda ubushyuhe, sima yigenga, putty, sima yo gusiga, sima yo gushushanya, sima ihuza ibintu, sima yo gusana n'ibikoresho bifunga amazi, nibindi. Uburyo bwo gukoresha sima yo kubaka n'imikorere yayo. Birumvikana ko hari ibibazo byo guhuza hagati y'ifu ya latex ishobora guhindurwa na sima, ibintu bivanze n'ibintu bivanze, ibyo bikaba bigomba kwitabwaho bihagije mu bikorwa byihariye.
