Super absorbent polymers yakagadzirwa mukupera kwema1960.Muna 1961, Northern Research Institute yeU.S. Department of Agriculture yakabatanidza starch kuacrylonitrile kekutanga kugadzira HSPAN starch acrylonitrile graft copolymer yaipfuura zvechinyakare zvinonwisa mvura.Muna 1978, Sanyo Chemical Co., Ltd. yekuJapan yakatungamira mukushandisa mapolymer akanyanya kunyura pamadiapers anoraswa, izvo zvakakwezva kutarisisa kwesainzi kubva pasirese.Mukupera kwema1970s, UCC Corporation yeUnited States yakaronga kuyambuka-siyana olefin oxide polymers neradiation kurapwa, uye synthesized asiri-ionic super absorbent polymers ane simba rekunyudza mvura ka2000, nekudaro achivhura synthesis yeasiri-ionic. super absorbent polymers.Door.Muna 1983, Sanyo Chemicals yekuJapan yakashandisa potassium acrylate pamberi pemakomisheni ediene akadai semethacrylamide kuita polymerize superabsorbent polymers.Mushure meizvozvo, kambani yakaramba ichigadzira akasiyana-siyana superabsorbent polymer masisitimu anoumbwa neakagadziridzwa polyacrylic asidhi uye polyacrylamide.Pakupera kwezana ramakore rapfuura, masayendisiti kubva kunyika dzakasiyana-siyana akatevedzana akagadzira uye akaita kuti superabsorbent polymers ikure nekukurumidza munyika dzepasirese.Parizvino, mapoka matatu makuru ekugadzira eJapan Shokubai, Sanyo Chemical uye Stockhausen yeGermany akagadzira mamiriro ane makumbo matatu.Ivo vanodzora makumi manomwe muzana emusika wepasirese nhasi, uye vanoitisa mubatanidzwa wepasi rose kuburikidza nekubatana kwehunyanzvi kudzora misika yepamusoro yenyika dzese pasirese.Kodzero yekutengesa mapolymer anonwisa mvura.Super absorbent polymers ane huwandu hwakasiyana hwekushandisa uye yakakura kwazvo tarisiro yekushandisa.Parizvino, kushandiswa kwayo kukuru kuchiri zvigadzirwa zvehutsanana, zvichiverengera nezve 70% yemusika wese.
Sezvo sodium polyacrylate superabsorbent resin ine simba rakakura rekunyudza mvura uye kuita kwakanakisa kwekuchengetedza mvura, ine huwandu hwakasiyana hwekushandisa sechinhu chekuchengetedza mvura yevhu mukurima nemasango.Kana chidimbu chidiki chesodium polyacrylate chikaiswa muvhu, kumera kwedzimwe bhinzi uye kusanaya kwemvura kwebhinzi kunogona kuvandudzwa, uye kupinza kwemhepo kwevhu kunogona kuvandudzwa.Uye zvakare, nekuda kweiyo hydrophilicity uye yakanakisa anti-fogging uye anti-condensation zvimiro zve super absorbent resin, inogona kushandiswa sechinhu chitsva chekurongedza.Iro firimu rekurongedza rakagadzirwa neakasarudzika zvimiro zve super absorbent polymer rinogona kunyatso chengetedza kutsva kwechikafu.Kuwedzera huwandu hushoma hwepolymer inonyudza kune zvizorwa zvakare inogona kuwedzera viscosity yeemulsion, inova yakanaka thickener.Uchishandisa hunhu hwe super absorbent polymer inongotora mvura chete asi kwete mafuta kana organic solvents, inogona kushandiswa senge inopedza mvura muindasitiri.
Nekuti mapolima akanyanya kunyura haana chepfu, haatsamwire muviri wemunhu, asiri-padivi maitiro, uye asiri-yeropa coagulation, ave achishandiswa zvakanyanya mumunda wemishonga mumakore achangopfuura.Semuenzaniso, inoshandiswa kumafuta ekuzora ane mvura yakakwirira uye akasununguka kushandisa;kugadzira mabhandeji ekurapa uye mabhora ekotoni anogona kutora kubuda ropa uye zvakavanzika kubva pakuvhiyiwa uye kushungurudzika, uye anogona kudzivirira suppuration;kugadzira anti-bacterial agents anogona kupfuudza mvura nemishonga asi kwete tupukanana.Infectious artificial skin, etc.
Nekuvandudzwa kwesainzi uye tekinoroji, kuchengetedza kwezvakatipoteredza kwakakwezva kutarisisa kwakawanda.Kana iyo super absorbent polymer ikaiswa mubhegi rinonyungudika mutsvina, uye bhegi racho rikanyudzwa mutsvina, kana bhegi ranyungudutswa, iyo super absorbent polymer inogona kukurumidza kutora mvura kuomesa tsvina.
Muindasitiri yezvemagetsi, mapolima akanyanya kunyura anogona zvakare kushandiswa senge humidity sensors, mwando kuyerwa sensors, uye mvura inodonha inoongorora.Super absorbent polymers inogona kushandiswa seheavy metal ion adsorbents uye zvinhu zvinotora mafuta.
Muchidimbu, super-absorbent polymer imhando yezvinyorwa zvepolymer zvine huwandu hwakawanda hwekushandisa.Iko kukura kwakasimba kweiyo super-absorbent polymer resin ine yakakura musika mukana.Gore rino, pasi pemamiriro ekusanaya kwemvura uye kuderera kwemvura munzvimbo zhinji dzekuchamhembe kwenyika yangu, nzira yekuenderera mberi nekusimudzira nekushandisa superabsorbent polymers ibasa rekukurumidzira rakatarisana nekurima nemasango masayendisiti uye matekiniki.Munguva yekuitwa kweWestern Development Strategy, mubasa rekuvandudza ivhu, kusimudzira nesimba uye kushandisa akawanda anoshanda mabasa emapolymers akanyanya kunyura, ane chokwadi chemagariro uye zvinogona kubatsira mune zvehupfumi.Zhuhai Demi Chemicals inovhara nzvimbo inopfuura 30,000 square metres.Iyo inonyanya kutsvagisa uye kusimudzira uye kugadzirwa kwezvinhu zvakanyanya kunyura zvinhu (SAP) zvine hukama zvigadzirwa.Ndiyo yekutanga kambani yepamba inobatikana mune yakanyanya kunyura resin inosanganisa tsvakiridzo yesainzi, kugadzira, kutengesa, uye masevhisi ehunyanzvi.high-tech mabhizimisi.Iyo kambani ine yakazvimirira kodzero yezvivakwa, tsvakiridzo yakasimba uye kugona kusimudzira, uye inogara ichivhura zvigadzirwa zvitsva.Chirongwa ichi chinosanganisirwa muchirongwa chenyika che “torch plan” uye chakarumbidzwa kakawanda nehurumende dzenyika, matunhu nemanisipala.
Nzvimbo Yekushandisa
1. Zvikumbiro mukurima nekurima
Iyo super absorbent resin inoshandiswa mukurima uye horticulture inonzi zvakare inochengetedza mvura mumiriri uye ivhu conditioner.nyika yangu inyika ine kushomeka kwakanyanya kwemvura munyika.Nokudaro, kushandiswa kwemishonga inochengetedza mvura kunowedzera kukosha.Parizvino, anopfuura gumi nemaviri masangano ekutsvagisa emumba akagadzira zvigadzirwa zvinonwisa resin zvezviyo, donje, oiri, uye shuga.Fodya, michero, miriwo, masango uye mamwe marudzi anopfuura makumi matanhatu emiti, nzvimbo yekusimudzira inopfuura mahekita makumi manomwe, uye kushandiswa kwepamusoro-soro kunyura resin muNorthwest, Inner Mongolia nedzimwe nzvimbo dzenzvimbo huru yejecha kudzora kudyara kwemasango.Iwo akanyanya kunyura resin anoshandiswa muchikamu ichi anonyanya kubatanidzwa acrylate polymer cross-linked zvigadzirwa uye acrylamide-acrylate copolymer cross-linked zvigadzirwa, umo munyu wachinja kubva kurudzi rwesodium kuenda kumhando yepotassium.Nzira huru dzinoshandiswa ndedzekupfekedza mhodzi, kupfapfaidza, kuisa gomba, kana kunyura midzi yechirimwa mushure mekusanganiswa nemvura kugadzira dovi.Panguva imwecheteyo, iyo super absorbent resin inogona kushandiswa kupfekedza fetiraiza yobva yaisa fetereza, kuitira kupa kutamba kwakazara kune mwero wekushandiswa kwefetereza uye kudzivirira marara uye kusvibiswa.Nyika dzekune dzimwe nyika dzinoshandisawo super absorbent resin sezvitsva zvekurongedza zvinhu zvemichero, miriwo uye chikafu.
2. Zvikumbiro mune zvekurapa uye zvehutsanana zvinonyanya kushandiswa sehutsanana napkins, vana manapukeni, napkins, kurapwa ice packs;gel-kufanana nezvinhu zvinonhuhwirira zvekushandisa zuva nezuva kugadzirisa mamiriro ekunze.Inoshandiswa sechinhu chekutanga chekurapa kwezvizoro, makirimu, liniments, cataplasms, nezvimwewo, ine mabasa ekunyorovesa, kukora, kupinza ganda uye gelation.Inogonawo kugadzirwa mutakuri akangwara anodzora huwandu hwemushonga unoburitswa, nguva yekuburitsa, uye nzvimbo yekuburitsa.
3. Kushandisa muindasitiri
Shandisa iyo super absorbent resin kunwisa mvura pakupisa kwepamusoro uye kuburitsa mvura pane tembiricha yakaderera kugadzira maindasitiri hunyoro-proof agent.Mumafuta ekudzoreredza oiri mashandiro, kunyanya munzvimbo dzekare dzemafuta, kushandiswa kweyepamusoro-yepamusoro mamorekuru uremu polyacrylamide aqueous mhinduro dzekutamisa mafuta kunoshanda zvakanyanya.Inogona zvakare kushandiswa kudzikisa mvura yeorganic solvents, kunyanya kune organic solvents ine yakaderera polarity.Kune zvakare maindasitiri anokora, pendi anonyungudika nemvura, nezvimwe.
4.Kushandisa mukuvaka
Zvinhu zvinokurumidza kuzvimba zvinoshandiswa mumapurojekiti ekuchengetedza mvura yakachena super inonwisa resin, iyo inonyanya kushandiswa kuvharisa tunzira dzemadhamu munguva yemafashamo, uye kuvhara mvura yemajoini akagadzirwa edzimba dzepasi, tunnels uye subways;inoshandiswa kugadzirisa tsvina yemumaguta uye mapurojekiti ekuchera Madhaka anoomesa kuti afambise kuchera nekufambisa.
