1. Mwachidule
Obwezeretsedwanso ma polima (RDP) ndi gulu lofunikira lazowonjezera lomwe limagwira ntchito yofunika kwambiri pakupanga zomatira ndi zimbudzi. Ma pointer awa nthawi zambiri amakhala mu ufa wa ufa ndipo amatha kubadwa m'madzi kuti apange emulsion, potero kupereka zinthu zomwe zingapangitse kuti katundu akhale. RDP imagwiritsidwa ntchito kwambiri pomanga, zokongoletsera panyumba ndi mafakitale. Ntchito zake zazikulu zimaphatikizanso kukonza zomatira, kulimbitsa kusinthasintha, kukonza mayendedwe ndi kukulitsa madzi.
2. Kapangidwe ndi mitundu ya obwezeredwa
Obwezeretsedwanso ma polipo nthawi zambiri amakhala opangidwa ndi a Vinyll acetate cololymer (Eva), stylene covolymer (sbyll acetate worlolymer (sbyl), etc. Pambuyo poyimitsa utsi, ufa chifukwa chofatsa amatha kukonzanso emulsion mutatha kuwonjezera madzi.
Magwiridwe antchito ndi magwiridwe antchito a rdp amagwirizana kwambiri ndi kapangidwe kake. Mwachitsanzo:
Eva: Ili ndi katundu wogwirizira ndi madzi abwino ndipo amagwiritsa ntchito madzi ndipo nthawi zambiri amagwiritsidwa ntchito m'masamba a mataoma ndi khoma la khomalo.
SBR: Kusinthasintha kosinthasintha komanso kuvala kukana, choyenera chosinthika ndi zokutira zowonongeka.
Vae: Kuphatikiza zabwino za Eva ndi SBR, zimagwiritsidwa ntchito kwambiri pamitundu yosiyanasiyana yomwe imafunikira magwiridwe antchito.
3. Udindo Wamaterites
Mu zomatira, RDP imagwiritsidwa ntchito makamaka pokonzekera kulimba ndi kusinthasintha. Maudindo ake enieni ndi monga:
3.1 Kukonzanso ntchito
RDP imatha kusintha mogwirizana chotsatsa cha zomata za magawo osiyanasiyana, makamaka pamphamvu komanso yodzipereka. Mwachitsanzo, kuwonjezera rdp ku zomata za tile kumatha kukulitsa mphamvu ndi kukana madzi, potero kufalitsa moyo wa matailosi.
3.2 Kuwongolera kusinthasintha
Kusinthasintha ndi imodzi mwazomwe zimachitika zomatira zomatira, makamaka pochita ndi kusintha kwa kutentha kapena kusamuka. Kuphatikiza kwa rdp kumatha kupereka kusinthasintha bwino ndikuchepetsa chiopsezo cha kuwonongeka kapena kuyika. Izi ndizofunikira makamaka pazinthu zapakatikati komanso zakunja, makamaka madera omwe ali ndi kutentha kwa kutentha.
3.3 Kuwongolera madzi ndi ntchito zomanga
RDP imatha kusintha madzima amalonda, kupangitsa kuti azitha kugwiritsa ntchito komanso kusintha panthawi yomanga. Madzi abwino samangokonda kusintha mphamvu yomanga, komanso amatsimikizira kufanana kwa zomatira, potengera mgwirizano.
4. Udindo wa Zisindikizo
RDP imagwiranso gawo lofunikira pakupanga zisindikizo. Udindo wake waukulu ukuwonekera m'mbali zotsatirazi:
4.1 Kukhazikitsa Kuchita Kuchita
RDP imatha kupanga filimu yovuta ya polymer mu sealant kuti ipititse mphamvu ya mpweya ndi kuthira madzi a sealant. Izi zimathandiza kwambiri pakumanga mafupa ndi kusindikiza mafakitale, makamaka mu chinyontho.
4.2 Kukana nyengo
Kukana nyengo yabwino ndi chitsimikizo chofuna kugwiritsa ntchito zigawo zazitali. Kuphatikiza kwa rdp kumatha kukulitsa kukana kwa chisindikizo ku chilengedwe monga a Ultraviolet Rays ndi Ozone, ndikuwonjezera moyo wa chosindikizira.
4.3 Kupereka zotukuka komanso kulimba
RDP imatha kupatsa zitseko zabwino komanso kulimba mtima, kotero kuti zitha kubwerera msanga potengera mphamvu zakunja kapena kuphatikizika kwa gawo lapansi, kupewa kusokonekera ndikugwa.
5. Maganizo pakupanga kapangidwe kake
Mukamagwiritsa ntchito rdp mu mapangidwe a zomatira ndi zosindikizira, zinthu zotsatirazi zofunika kuzilingalira:
5.1 Kusankhidwa kwa RDP
Sankhani mtundu woyenera malinga ndi zomwe mukufuna. Mwachitsanzo, kwa zomatira zomwe zimafuna kulimbikira mphamvu kwambiri, iva imasankhidwa; Kwa zigawo zam'madzi ndi zofunikira kwambiri, ntzingse-zochokera ku SBBR ikhoza kusankhidwa.
5.2 Kuwongolera kwa Mlingo
Mlingo wa rdp umakhudza mwachindunji magwiridwe antchito ndi zimbudzi. Zambiri za RDP zitha kubweretsa ndalama zochulukirapo, pomwe zochulukirapo kwambiri sizitha kukwaniritsa zomwe zikuyembekezeka. Chifukwa chake, ndikofunikira kuti muziwongolera malinga ndi zosowa zenizeni ndi kapangidwe kake.
5.3 Synergy ndi zina zowonjezera
RDP nthawi zambiri imagwiritsidwa ntchito ndi zina zowonjezera (monga otsatsa, detomers, sobere inhibitors, etc.) kuti mukonze magwiridwe antchito. Mukamapanga kupanga, ndikofunikira kuganizira momveka bwino za mdera lililonse kuti awonetsetse kuti magwiridwe omaliza ndi oyenera.
Obwezeretsedwanso ma polima amakhala ndi mtengo wogwiritsira ntchito mogwirizana ndi mapangidwe a zomatira komanso zosindikizira. Mwa kusankha ndi kugwiritsa ntchito RDP, magwiridwe antchito ndi zigawo zitha kusintha kwambiri kuti akwaniritse zosowa za prenarios yosiyanasiyana. M'tsogolo, chifukwa cha chitukuko cha ukadaulo ndi kusintha kwa kufunika kwa msika, chiyembekezo chogwiritsa ntchito cha rdp muzinthu zatsopano ndipo kutetezedwa kwa chilengedwe ku Green kudzakhala kotalika.
