Polima konkire: zikuchokera, mitundu, maonekedwe, ntchito ndi luso ndemanga

Polima konkire - wapadera zomangila, amene ntchito ngati binder ndi, komanso m'malo a kupanga laimu. Mu zina, polima ntchito monga Kuwonjezera simenti Portland. Ndi mosalekeza, cholimba gulu chuma analandira mwa kusakaniza fillers zosiyanasiyana mchere ndi wothandizila kupanga kapena zachilengedwe astringent. Izi patsogolo zomangamanga kugwiritsidwa ntchito m'mafakitale ambiri, koma ndi ambiri mu zomangamanga.

mitundu

Kumangako ntchito mitundu itatu ya polima konkire. Kenako, tione luso yopanga awo, kukula ndi kapangidwe ndi chithunzithunzi cha polima konkire ndi zosintha awo.

Polima nyimbo yowona (simenti ndi polima-kusinthidwa)

Mtundu uwu wa simenti anapangidwa kuchokera Portland zinthu simenti ndi polima kusinthidwa monga akiliriki, polyvinyl nthochi ndi ethylene vinilu nthochi. Ali guluu wolimba wabwino, mkulu flexural mphamvu ndi otsika permeability.

Akiliriki polima kusinthidwa konkire amakhala ndi mtundu wolimbikira, limene ndi chifukwa chake zikufunika kwambiri mwa omanga ndi mapulani. kusinthidwa ake mankhwala ndi ofanana ochiritsira simenti kusintha. Kuchuluka kwa polima zambiri Mitandadza 10 20%. Konkire, kusinthidwa mu njira iyi amamva apansi permeation ndi osalimba kuposa simenti koyera. Komabe, kukhulupirika kwake structural zimatengera kwenikweni pa binder simenti Portland.

kudzitsitsa konkire Zingatenge nthawi yaitali ngati ali osalimba mkulu ndi dera ang'onoang'ono pamwamba. Kupititsa wachibale mankhwala bata wa polima-kusinthidwa chuma Portland simenti mulole mu sing'anga acidic.

Utomoni impregnated konkire

A impregnation utomoni kwa konkire amakhalabe ndi kuyambitsa monomer mu otsika kachulukidwe hydrated Portland simenti, kenako cheza kapena matenthedwe polymerisation chothandizira. Kusinthasintha yodziyimira payokha a mtundu wa simenti ndi 50-100% kuposa pafupifupi.

Komabe, polima modulus 10% kuposa konkire yachibadwa. Chifukwa cha makhalidwe amenewa kwambiri, pakati pa kuchuluka kwa mungachite ntchito polymeric kumanga zinthu zikhoza payokha otchulidwa kupanga:

• adzikometsa;
• milatho;
• mipope;
• matailosi pansi;
• laminate yomanga.

kuyambitsa ndondomeko luso zikuphatikizapo simenti-kuyanika kuchotsa chinyezi kuchokera pamwamba, ntchito monomers mu wosanjikiza woonda mchenga, ndiyeno polymerizing monomers ntchito kutentha kamwazi. Choncho, pamalo simenti ndi m'munsi permeability madzi, mayamwidwe, kukana kumva kuwawa ndi mphamvu zambiri mkulu. Komanso, kusintha avale kukana, kukana kuti ozizira ndi chinyezi, ntchito polymeric zokutira kwa simenti, njerwa, miyala, simenti, etc.

polima

Izo ziribe kanthu kochita ndi alipidwa kwa ife Portland. Popangidwa ndi miyala osakaniza ndi polymeric binder zinthu zomwe lilibe madzi. Polystyrene, akiliriki ndi epoxy resins ndi monomers zomwe ankagwiritsa ntchito kupanga mtundu wa simenti. Sulfa amadziwikanso ankamuona ngati polima a. Sulfa konkire ntchito nyumba ofunika kukana mkulu mapangidwe acidic. ma polima Thermoplastic koma zambiri thermosetting utomoni ntchito monga waukulu chigawo utomoni chifukwa cha matenthedwe bata awo okwezeka ndi kukhazikika osiyanasiyana mankhwala.

Polymeric konkire wapangidwa mayunitsi monga silika, khwatsi, lubwe, miyala ndi zinthu zina khalidwe. Unit ayenera kukhala wabwino ndi ufulu wa fumbi, zinyalala ndi chinyezi owonjezera. Satsatira akwaniritsa zimenezi akhoza kuchepetsa chomangira mphamvu pakati pa binder polymeric ndi filler.

Makamaka polima konkire

Modern chuma nyumba wosiyana akalambula ake. Ilo liri ndi makhalidwe awa:

• Zonyamula mapangidwe mankhwala ndi kwachilengedwenso.
• Poyerekeza ndi mankhwala simenti-simenti, lili zochepa misa.
• Mwangwiro zimatenga phokoso ndi Phokoso.
• Vyvetrivaemost ndi zabwino UV kukana.
• Mayamwidwe madzi.
• Iwo akhoza kudula ntchito akufa pochita ndi grinders.
• Izo zikhoza kukonzedwa ngati mwala wosweka kapena kum'pondereza ntchito monga m'munsi msewu.
• About 4 nthawi wamphamvu kuposa konkire simenti.
• katundu wabwino kutchinjiriza ndi kukhazikika.
• Kopitilira muyeso-mapeto, uyenera kuthandiza imayenera hayidiroliki otaya.

ntchito

Polima angagwiritsidwe ntchito yomanga latsopano kapena kukonzanso chuma akale. katundu zomatira kulola ayambe kwa polima ndi ochiritsira konkire, simenti-maziko. Low permeability ndi kukana dzimbiri kulola ntchito m'madamu kusambira, kachitidwe zimbudzi, njira ngalande, maselo electrolytic ndi nyumba zina munali zakumwa kapena mankhwala onyeketsa. Ndi oyenera pa ntchito yomanga ndi konzanso zitsime, chifukwa mphamvu yake kupewa mpweya woipa komanso zikuwononga kuchimbudzi ndi mabakiteriya ambiri amene machitidwe madzi.

Mosiyana ndi nyumba za makolo simenti, izo sikutanthauza ❖ kuyanika kapena kuwotcherera seams kutetezedwa PVC. Mukhoza kuona ntchito polima konkire m'misewu. Ndi ntchito yomanga zopinga pa msewu, msewu, mphepete mwa ngalande, akasupe. Komanso mu msewu ndi polima ❖ kuyanika kwa konkire anawonjezera kuti phula pa ntchito yomanga malo panja, runways ndi zipangizo zina zimene zili panja ndipo kaŵirikaŵiri ndi weathering kunja.

Reviews

The polima konkire sichinayambe ambiri anatengera chifukwa cha ndalama yapamwamba ndi mavuto kugwirizana ndi umisiri mwambo opanga. Komabe, patsogolo posachedwapa zachititsa kuti kuchepetsa kwambiri ndalama, kutanthauza kuti ntchito yake ayamba wamba. Ngakhale ubwino wake onse pa ochiritsira simenti, ndi malingaliro za zobisika zinthu zoipa chilengedwe amayambira chifukwa zosayenera kupanga, kugwiritsa ntchito zigawo zikuluzikulu otsika kwambiri ndi kuphwanya kufanana.

Komanso, sayansi ya ulimi wa polima konkire ali zambiri mokoma ndi zinsinsi kuti palibe amene amafuna kuwulula. Ndipo ndithudi, monga taonera ndi ndemanga, mtengo polima msika si mkulu. Ichi ndi chifukwa n'kovuta kupanga ake, ndi mbali mtengo, amene ntchito kulenga izo.
