Ukudweba ngekhonkrithi. Ukukhetha, izici, amanani

Naphezu kwamandla aphezulu nokuhlala isikhathi eside, indawo yokukhonkolo ijwayele ukukhishwa kwe-chips, ukuhlasela kwamakhemikhali nokulimala komshini. Indlela elula yokuyivikela ukuwubala. Ukupenda okukhethiwe ngokufaneleko kokhonkolo, ngokungeziweko, kuthuthukisa khulu ubujamo bokubukeka kwalesi sakhiwo.

Umsebenzi wokuvikela upende

Ngokuvamile, ngenxa yokugqoka kwendawo yokukhonkolo, udumo olubonakalayo lubonakala kuso. Lokhu kungenxa ye-porosity ephakeme yalokho okushicilelwe, futhi kungenzeka ngenxa yekhwalithi yayo embi noma ukwephulwa kobuchwepheshe be-stacking. Amakhemikhali akhethekile, asetshenziselwa ukudweba ukhonkolo, azosiza ukuvikela ubuso ukuthi bangagqoki, ukubhujiswa nokuvezwa kwendawo enonya.

Ngaphezu kwalokho, imakethe inikeza umbala obala wombala wezinhlobonhlobo ezinjalo, okwenza kube lula ukukhetha ukwakheka kwanoma iyiphi ingaphakathi. Ukugcina phansi ukhonkolo kwenza kube ngcono, kuhlinzekela ukunakekelwa nokufihla zonke izinhlobo zokukhubazeka ebusweni.

Izinhlobo zamapende okukhonkolo

Lapho ukhetha upende, kufanele ucabangele izici zohlu. Ezindaweni lapho ukulimala komzimba ngenxa yomthelela wokufaka umthelela kungenzeka, ukugqoka okuthembekile okudingekayo kuyadingeka.

Amapayipi akhethekile wekhonkrithi - okugqoke ukugqoka, aqukethe ama-solvents nama-epoxy koqweqwe lwawo - uzobhekana ngokugcwele nalo msebenzi. Azisetshenziselwa izakhiwo zezimboni kuphela, kodwa futhi nasegaraji, izindawo zokupaka, ama-hangars, izitolo zokulungisa, njll.

Izindonga zangaphakathi noma zangaphandle, ikakhulukazi amapende ase-acrylic (organic and aqueous) asetshenziswa. Izambatho zendawo yokukhonkolo kanye nokwakheka kwamakhemikhali ziqinile ikakhulukazi, zingamelana nemithonya ehlukahlukene yemvelo enonya. Ukudweba kwekhonkrithi esekelwe ngamanzi akunamandla kangako, kodwa ezindlini zangasese, lapho kungekho mthwalo ophezulu ezinkampanini, njengasezindaweni zezimboni, zisetshenziswa kabanzi ngabanikazi abaningi bezakhiwo zangasese.

Amapende we-Acrylic

Lokhu kuyakheka okunamandla okusekelwe ku- resin yama-acrylic ngokufakwa kwezingulube eziphilayo nezemibala. Ipeyinti yakha ukugqoka okuqinile futhi ifanele ukwelashwa kwezakhiwo zekhonkrithi emagalaji, izindlu zangasese, amakamelo okusiza kanye nezakhiwo zokukhiqiza, kuma-balconi. Ifilimu ye-polymer eyakhayo kuyisithiyo esibi emiphakathini ehlukahlukene yamakhemikhali nemishini, evikela ukhonkolo ekushiseni.

Amacici e-Acrylic okhonkolo ayenempilo kakhulu. Badla ngokushesha futhi abanakho iphunga elinamandla. Ngaphezu kwalokho, ayamelana nomswakama kanye nokushisa okuphezulu. Basebenzisa nge-shayela, i-roller noma nge-sprayer yepende, ngokuvamile u-one ungqimba uyanele. Musa nje ukusebenzisa ama-acrylic ama-epoxy noma i- polyurethane yokugqoka. Inzuzo enkulu kunemibala ehlukahlukene, kuhlanganise nemibala, i-matt ne-glossy imibala. Izindleko ziphakathi kwama-ruble angu-100-150 nge-1 kg.

Amapayipi e-Epoxy

Izinzuzo eziyinhloko zalezi zakhiwo yikhono labo lokunikeza amandla aphakeme nokuphila kwesikhathi eside sokugqoka. Ukudweba okunjalo kungamelana nemithwalo ebalulekile futhi engesabi imiphumela ye-acids, i-alkali, izixazululo zelinisi namafutha kanye namafutha. Ukwakheka kuhlelwe ngobuso bekhonkrithi, abuphenduli ngesikhatsi futhi kungavumeli, ngakho-ke kungasetshenziswa ezindaweni ezinezimoto eziphezulu.

Ngenxa yokumelana kwayo nezimo ezihlukahlukene zendawo, angasetshenziselwa kuphela izakhiwo zangaphakathi, kodwa futhi njengopende yangaphandle (ngaphandle, ukupaka izimoto).

Ukungahleleki kungabonakala ukuthi ukubunjwa kwamakhemikhali amabili okudweba kudinga ukuxuba okuphoqelekile ngaphambi kokufaka isicelo. Futhi kunzima nakakhulu esikhathini esizayo ukushintsha umbala wengubo, ngakho-ke udinga ngokushesha ukuthi ukhethe ukukhetha okufanele kakhulu.

Intengo ngayinye ye-1 kg yepopu ye- epoxy yekhonkrithi ivela kuma-250 kuya ku-500 r nge-1 kg.

I-Polyurethane koqweqwe lwawo

Inzuzo enkulu yale peyinti yikhono layo lokudala ukugqoka okwesibhakabhaka okupholile. Kuyafaneleka kokubili umsebenzi wangaphakathi nangaphandle. Naphezu kokuthi ukubunjwa kwalo kuyingxenye ezimbili, kunekhwalithi enhle kakhulu. Kanye nezakhiwo ezinjengokumelana nemonakalo ehlukahlukene, emathonyeni angaphakathi emoyeni kanye nobungane bomhlaba, ukudweba kwe-polyurethane yokukhonkxa kunomnotho kakhulu kwisicelo, kunamandla okumboza.

Umdwebo usetshenziselwa ukushisa kwomoya okungenani u-5 ° C, futhi umswakama ohlobene kufanele ungadluli 75%. Ukudweba kwendawo yokukhonkolo kwenziwa ngezitezi ezimbili. Isicelo sesibili senziwe kungakapheli amahora angu-24 ngemuva kokuqala. Isigqoko sizinzile ngokuphelele emva kwezinsuku ezingu-7. Amanani amakhulu ancike kakhulu kumakhi nomkhiqizo. Ngokwesilinganiso, ukuthengwa kwe-10 kg ye-koqweqwe lwawo kubiza ama-ruble angu-2800-3000. I-polyurethane ukudweba ukhonkolo kubhekwa njengento ezuzisayo futhi ewusizo kakhulu ekuqedeni.

Amaphoyinti e-facade

Njengomthetho, izidingo eziphakeme kakhulu zifakwe ezintweni zokwakha umcabango. Ngaphandle kokunikeza ukubukeka okukhangayo ekwakheni, kumele bame ukubhekana nemiphumela yazo zonke izinhlobo zamakhemikhali nezinguquko zokushisa, ukuphikisana nokushisa, imisebe ye-ultraviolet, u-fungus kanye nenkuni, futhi ube nezinga elanele lokuphefumula.

Ukuze upende ngalezi zinto ngokucophelela, uhlaka olukhethekile oludweba ukukhonjiswa lusetshenziselwa, olunezo zonke izici ezingenhla. Kungaba kokubili i-polyurethane, kanye nezingoma ze-acrylic emanzini noma kwi-solvents ephilayo.

Isikhathi sokuphila sopende lobukhoma sincike ekutheni izinga lokunamathela, ngakho-ke lapho ukhetha izinto zokuqeda, kufanele uqaphele ngokukhethekile kulabo okuyi-acrylic kanye ne-vinyl resins, i-glass potassium, i-lime noma i-samente yi-agent ebophayo.

Imibala ye-Rubber

Umkhiqizo wesizukulwane esisha ubizwa ngokuthi lokhu okubonakalayo kokuphela kokugcina. Lo mdwebo ufanelekile ukucubungula kokubili okumile futhi okumanzi. Ngenxa yokwakhiwa kwayo, ukumboza okunjalo ngeke kuphephe futhi ngeke kuphele, kunomthelela kakhulu kumathini wokuthinta. Ngokungenabungozi ekubunjweni komzimba womuntu kunamapulangwe enjoloba ngokukhonkolo. Ukunakekela ukugqoka okunjalo kulula, nje ugeze ngesipho. Ukudala ifilimu engashoni elangeni, upende luvikela ubuso bekhonkrithi emthelela omubi wendawo, ngenkathi uvumela ukuba uphefumule.

Enye yezinzuzo zalezi zinhlanganisela ukuthi ubuso obuphathwe yizo zakhiwo eziphikisayo, futhi lokhu kubaluleke kakhulu phansi. Ngenxa yomdwebo wombala obanzi, ohlukanisa amapayipi enjoloba ukhonkolo, abagcini nje kuphela ukufeza indima yokugqoka imfanelo, kodwa futhi kufanelekile ukuxazulula noma yimuphi umqondo wokuklama. Intengo yekhilimu eyodwa yepende kusuka ku-120 p nangaphezulu.
