Ngenxa yokuqina kwayo okuphezulu kunye neendleko eziphantsi, ikhonkrithi yeyona nto isetyenziswa kakhulu kwisakhiwo sokwakha.Nangona kunjalo, ngenxa yobunzima bayo obukhulu, ukuqhekeka ngokulula, ukuchasana nempembelelo ephantsi kunye nezinye iziphene, ithintela uphuhliso lwayo olongezelelweyo.Ukusetyenziswa kwemicu ye-organic synthetic ukuguqula ikhonkrithi kunokuphucula kakhulu okanye kuphuculwe ukuxhathisa kokuqhekeka kwekhonkrithi, ukunciphisa isizukulwana kunye nophuhliso lweentanda, kunye nokuphucula ukusebenza okubanzi kwekhonkrithi ngokubanzi.
1.1 Yandisa ukuxhathisa kokuqhekeka kwekhonkrithi
Kulwakhiwo lwangempela lwekhonkrithi, ngenxa yobukho bokufuma okugqithisileyo, ubushushu obukhulu be-hydration buveliswa kwinkqubo yokuxuba, ukuqhekeka kweplastiki ye-shrinkage kulula ukwenzeka kwinkqubo yokugalela kunye nokwenza, ukuqhekeka okomileyo kwenzeka xa ulahlekelwa ngamanzi kwaye ukomisa, kunye nokuqhekeka kweqondo lokushisa kwenzeka ngenxa yokutshintsha kweqondo lokushisa kwinqanaba lokuqina.Ukwenzeka kweentanda ezinjalo kunempembelelo enkulu kwiipropati zomatshini, ukungakwazi ukunyanzeliswa kunye nokuqina kwekhonkrithi.Ukongeza inani elincinci le-organic fiber (ngokubanzi i-0.05% ~ 1.0% yomthamo wekhonkrithi) kwikhonkrithi inokuphucula kakhulu okanye iphucule ukuxhathisa kokuqhekeka kwekhonkrithi.Ngenxa yokuba ifayibha eziphilayo a low elastic modulus ifayibha, ifayibha ngokwayo bhetyebhetye elungileyo, kwaye ingasasazwa kakuhle kwikhonkrithi ukwenza uthungelwano lwenkxaso chaotic ezintathu-ntathu, nto leyo enokuthintela kakuhle ukwenzeka iintanda kwinkqubo yokubumba yekhonkrithi, kwaye ngenxa yokuba i-fiber ine-adhesion ethile kwi-concrete, i-fiber ithwala uxinzelelo olubangelwa yi-deformation yeplastiki yekhonkrithi, ngaloo ndlela ikhusela ukukhula kunye nophuhliso lweentanda zakuqala, kunye nokuphucula kakhulu okanye ukuphucula ukuxhathisa ukuqhekeka.
1.2 Ukuphucula ukungakwazi ukungena kwikhonkrithi
Ikhonkrithi yinto edibeneyo edibeneyo, kukho i-micropores eninzi phakathi kwee-aggregates, kunye nenani elikhulu leempembelelo ze-capillary, kunye nokuqhekeka okuveliswa ngokumisa ikhonkrithi kunye nokuqina, okunciphisa ukunyanzeliswa kwekhonkrithi.Ukongeza inani elincinci le-organic fiber kwikhonkrithi liyakwazi ukusasazwa ngokulinganayo kwaye linamathele kakuhle kwikhonkrithi, elinciphisa okanye lithintele ukubunjwa, ukukhula kunye nophuhliso lweentanda kwikhonkrithi, ngakumbi ukunciphisa kakhulu isizukulwana sokudibanisa iintanda kunye nokunciphisa intambo. umjelo wokukhupha amanzi.Ngelo xesha, kwinkqubo yokwenza ikhonkrithi, ukufakwa kweefibers kwandisa amandla ayo okubopha ngaphakathi, ukwenzela ukuba amacandelo ekhonkrithi ahlanganiswe ngakumbi emva kokubunjwa, ukunciphisa ngokufanelekileyo ukuveliswa kwe-micro-permeability.Ngoko ke, ukufakwa kwee-organic fibers kwikhonkrithi kuphucula kakhulu ukungabonakali kwayo.
ILaizhou Kaihui Machinery Co., Ltd ngumvelisi oqeqeshiweyo weumgca wekhonkrithi wefiber extrusion.Wamkelekile ukuba uqhagamshelane nathi ukuze ufumane ulwazi oluthe kratya.
