Ukhonkolo polymer: Ukwakheka, izinhlobo, izici, isicelo kanye nobuchwepheshe Izibuyekezo

ukhonkolo polymer - a izinto zokwakha ezikhethekile, okuyinto esetshenziswa njengendlela yokuhlanganisa, kanye esikhundleni limestone ukuqinisa. Kwezinye izimo, i-polymer iqina isetshenziswa njengenhlangano Ngaphezu Portland usimende. Kuyinto isebenziseka ngezindlela eziningi, okuhlala isikhathi eside impahla esiyinhlanganisela etholwe ngokuxuba fillers ezihlukahlukene amaminerali nama ejenti ethu zokwenziwa noma yemvelo astringent. Lokhu kwaziswa ubunjiniyela eziphambili esetshenziswa izimboni eziningi, kodwa kuvamile kakhulu embonini yezokwakha.

izinhlobo

Lapho kwakhiwa wasebenzisa izinhlobo ezintathu polymer ukhonkolo. Ngokulandelayo, sihlolisise ubuchwepheshe ukukhiqizwa yabo, ububanzi kanye nokusungulwa ukuba nomqondo othile ngokuthi ukhonkolo polymer kanye ukuhlela kabusha yabo.

Polymer izingoma ukhonkolo (ukhonkolo polymer-modified)

Lolu hlobo ukhonkolo wenza kusukela Portland usimende impahla nge polymer Ushintshe ezifana acrylic, polyvinyl acetate futhi ethylene vinyl acetate. Ingabe adhesion ezinhle, okusezingeni eliphezulu amandla flexural futhi permeability ongaphakeme.

Acrylic polymer Ushintshe ukhonkolo libhekene umbala ophikelelayo, okuyinto kungani bayindlala kakhulu phakathi abakhi abaklami. ukuguqulwa kwalo chemical iyafana ezivamile usimende ukushintshashintsha. Inani polymer ngokuvamile zokhahlamba kusuka 10 kuya 20%. Ukhonkolo, ukushintshwa ngale ndlela has a degree engezansi permeation kanye kwabantu ephakeme kunaleyo usimende okumsulwa. Nokho, ubuqotho bayo kwesakhiwo kuncike ngokuyisisekelo ku isibopho of Portland usimende.

nokucekelwa ukhonkolo zingase zithathe isikhathi eside uma has a high density kanye surface area ezincane. Ubungcono isihlobo ukuzinza amakhemikhali impahla polymer-elungisiwe Portland may usimende e i osebenzelana ene-asidi.

Resin ukhonkolo elifakwe

A resin impregnation for ukhonkolo ngokuvamile enziwa nge-wethula monomer e ukuminyana ongaphakeme hydrated Portland usimende, kulandele ngemisebe noma ezishisayo polymerisation kulethe. Ukuzivumelanisa nezimo Modular of lolu hlobo eziphathekako ngokwenza 50-100% ingaphezulu kuka.

Nokho, i-polymer iqina Modulus 10% obukhulu kunobukaJohane ukhonkolo evamile. Ngenxa yalezi zici esihle, phakathi sebuningini ongakhetha ukusebenzisa polymeric impahla ukwakhiwa kungenziwa ngokwehlukana okukhulunywa ukukhiqizwa:

• onezitezi;
• amabhuloho;
• amapayipi;
• amathayili phansi;
• ukwakhiwa laminate.

ethula inqubo ubuchwepheshe kuhlanganisa ukhonkolo-omiswe ukususa umswakama ebusweni, ukusetshenziswa monomers e ungqimba ezondile esihlabathini, bese polymerizing le monomers usebenzisa ecucuza ukushisa. Ngakho-ke, evele ukhonkolo babe permeability ephansi amanzi, ukumuncwa, nemihuzuko ukumelana namandla komzimba. Futhi, ukuthuthukisa ukumelana ukuguga, ukumelana ezibandayo futhi umswakama, asetshenziselwa polymeric ezinengilazi for ukhonkolo, isitini, itshe, iphansi, njll

polymer

It has lutho nge evamile ukuba Portland. Ezakhiwe ngamatshe lihambisana polymeric isibopho impahla okungadingi zinamanzi. Polystyrene, acrylic epoxy inhlaka kukhona monomers iziphi kabanzi asetshenziswe ekukhiqizeni yalolu hlobo ngokhonkolo. Sulphur nayo ithathwa njengendlela polymer. Sulphur ukhonkolo sisetshenziswa izakhiwo ezidinga ukumelana nesimo ene-asidi. polymers Thermoplastic kodwa ngokuvamile thermosetting resin esetshenziswa njengoba main resin ingxenye ngenxa okusezingeni eliphezulu azinze ezishisayo nokuzinza anhlobonhlobo amakhemikhali.

ukhonkolo Polymeric yakhiwa amayunithi zihlanganisa Silica, asebenza ngebhethri, egwadle limestone kanye nezinye izinto izinga. Iyunithi kumele lube sezingeni eliphezulu futhi mahhala uthuli, doti futhi umswakama ngokweqile. Ukwehluleka ukulandela nalezi zindlela kunganciphisa amandla ubuhlobo obuphakathi kwabo isibopho polymeric kanye yamathebhu.

ukhonkolo polymer Ikakhulukazi

Modern yokwakha sihluke ezazingaphambi kwayo. It has izici ezilandelayo:

• ukumelana nesimo zamakhemikhali nezinto eziphilayo.
• Njengoba kuqhathaniswa imikhiqizo usimende-ukhonkolo, it has mass kancane.
• Ngokuphelele ubamba umsindo nokudludliza.
• Vyvetrivaemost nokuhle UV ukumelana.
• Ukunciphisa amanzi.
• It kungenziwa usike usebenzisa sokuzivivinya kanye grinders.
• Kungaba ukucubungulwa njengoba rock ochotshoziwe noma afahlazekile ukusetshenziswa njengoba base komgwaqo.
• Mayelana 4 izikhathi namandla kunomFilisti ukhonkolo usimende.
• Okuhle ukwahlukanisa izakhiwo nokuzinza.
• Ultra-sekugcineni, okuyinto kusiza kahle ukugeleza wokubacindezela.

ukusetshenziswa

Polymer ingasetshenziswa ukwakhiwa entsha noma kulungiswe izinto ezindala. Amandla ayo ingcina uvumele nokuvulwa kokubili polymer nokhonkolo ezivamile, usimende-base. permeability okuphansi futhi ukugqwala ukumelana ukuvumela ukusetshenziswa kwayo okubhukuda, zokuthuthwa kwetshe lentaba izinhlelo, iziteshi amanzi, amaseli electrolytic nezinye izakhiwo aqukethe zoketshezi noma amakhemikhali ezonakalisayo. Kuyinto efanelekayo ukwakhiwa kanye nokuhlumelelisa emithonjeni, ngenxa yekhono layo ukuze simelane ezinobuthi futhi onakalisayo amapayipi amagesi namagciwane ngokuvamile atholakala zamanzi.

Ngokungafani izakhiwo zikakhonkolo bendabuko, akudingi enamathela noma Welding ezivuzayo evikelwe PVC. Ungabona isicelo polymer aphathekako ezitaladini. Isetshenziselwa ekwakhiweni izithiyo endleleni, eceleni kwendlela amanzi ube nemigodi ngemigodi, imithombo yamanzi. Futhi emgwaqweni enamathela polymer for ukhonkolo yengezwe asphalt ekwakhiweni izindawo ongaphandle, zezindiza kanye nezinye izikhungo, okuyinto zitholakala endaweni evulekile kanye Njalo sibhekana weathering zangaphandle.

Izibuyekezo

I ukhonkolo polymer engakaze kabanzi bamukela ngenxa izindleko okusezingeni eliphezulu nangobunzima elihlobene ne bendabuko yokukhiqiza ubuchwepheshe. Nokho, intuthuko yamuva kuye eyabangela ukuncipha okukhulu ngo izindleko, okusho ukuthi ukusetshenziswa kwalo kuya kuvama. Naphezu kwakho konke zako phezu ukhonkolo ezivamile, banemibono mayelana kufihlwe ezintweni ezingezinhle kwemvelo ngokuvamile zenzeka ngenxa yokukhiqiza okungafanele, ukusetshenziswa izingxenye yekhwalithi ephansi kanye nokwephula ngezabelo.

Futhi, ubuchwepheshe ukukhiqizwa ukhonkolo polymer has a lot of umehluko wemisindo nemiqondo yamagama kanye izimfihlo ukuthi akekho sifuna ukuba embule. Futhi-ke, njengoba kwaphawula u-, inani polymer emakethe impela high. Lokhu kungenxa ubunzima ukukhiqizwa yayo, futhi izingxenye ezibizayo, ezisetshenziswa ukudala ke.
